[HTML] Using $ref of the same component in multiple properties of the same object causes only first property to appear

Swagger-codegen version

Docker image of swagger codegen cli version 3

Setup

Using powershell and docker by typing command

docker run -v path to swagger:/swagger.yaml -v path to output folder:/out swaggerapi/swagger-codegen-cli-v3 generate -l html -i /swagger.yaml -o /out

ISSUE

Lets take components:

 StringZeroOrOne:
      type: string
      enum: ["0", "1"]
      example: "1"
 TxHash:
      type: string
      minLength: 85
      maxLength: 85
      example: "0x28b2aa205726766fb5ffe79ca2d1d498c7dd2f579b2164db2017e5019713df61"
 PositiveStringFloatOrInt:
      type: string
      pattern: '^([0-9]*[.])?\d+$'
      example: "0.1241"
 DailyTradeSummary:
      type: object
      properties:
        id: 
         $ref: '#/components/schemas/TxHash'
        last: 
          $ref: "#/components/schemas/PositiveStringFloatOrInt" 
        percentChange: 
          $ref: "#/components/schemas/PositiveStringFloatOrInt" 
        high24hr:
          $ref: "#/components/schemas/PositiveStringFloatOrInt" 
        low24hr: 
          $ref: "#/components/schemas/PositiveStringFloatOrInt" 
        highestBid:
          $ref: "#/components/schemas/PositiveStringFloatOrInt" 
        lowestAsk:
          $ref: "#/components/schemas/PositiveStringFloatOrInt" 
        baseVolume:
          $ref: "#/components/schemas/PositiveStringFloatOrInt" 
        quoteVolume:
          $ref: "#/components/schemas/PositiveStringFloatOrInt" 
        isFrozen:  
          $ref: "#/components/schemas/StringZeroOrOne"

I use ref of PositiveStringFloatOrInt multiple times for the properties of one object

the UI response presents itself like this (after generating, in editor everything shows up fine):

  "last" : "0.1241",
  "id" : "0x28b2aa205726766fb5ffe79ca2d1d498c7dd2f579b2164db2017e5019713df61",
  "isFrozen" : "1"

From all the properties that had PositiveStringFloatOrInt referenced only the first one shows up which is the last property

Solution

Now if i replace the refs and repeat the code like this

 DailyTradeSummary:
      type: object
      properties:
        id: 
          $ref: '#/components/schemas/TxHash'
        last: 
          type: string
          pattern: '^([0-9]*[.])?\d+$'
          example: "0.5241"
        percentChange: 
          type: string
          pattern: '^([0-9]*[.])?\d+$'
          example: "0.3241"
        high24hr:
          type: string
          pattern: '^([0-9]*[.])?\d+$'
          example: "0.8241"
        low24hr: 
          type: string
          pattern: '^([0-9]*[.])?\d+$'
          example: "0.1111241"
        highestBid:
          type: string
          pattern: '^([0-9]*[.])?\d+$'
          example: "0.11"
        lowestAsk:
          type: string
          pattern: '^([0-9]*[.])?\d+$'
          example: "0.8241"
        baseVolume:
          type: string
          pattern: '^([0-9]*[.])?\d+$'
          example: "0.6241"
        quoteVolume:
          type: string
          pattern: '^([0-9]*[.])?\d+$'
          example: "0.1241"
        isFrozen:  
          $ref: "#/components/schemas/StringZeroOrOne"

The UI response shows up correctly

  "percentChange" : "0.3241",
  "high24hr" : "0.8241",
  "last" : "0.5241",
  "highestBid" : "0.11",
  "id" : "0x28b2aa205726766fb5ffe79ca2d1d498c7dd2f579b2164db2017e5019713df61",
  "quoteVolume" : "0.1241",
  "baseVolume" : "0.6241",
  "isFrozen" : "1",
  "lowestAsk" : "0.8241",
  "low24hr" : "0.1111241"

Start with the HTML generator invoked by the -l html command and reproduce the example using repeated $ref properties in DailyTradeSummary. Compare the generated output with the inline-schema version; the work is done when every property referencing PositiveStringFloatOrInt appears in the generated response.
