OpenAPI 3.0 dynamic HTML codegen crashes browser

I ran docker pull swaggerapi/swagger-codegen-cli-v3:3.0.11. Note that the latest generates an error so I pulled the latested tag, which was created 5 days ago. Also, if I use swaggerapi/swagger-codegen-cli, I get a com.fasterxml.jackson.core.JsonParseException: Unrecognized token 'openapi': was expecting ('true', 'false' or 'null') at [Source: (StringReader); line: 1, column: 8] error

Command:

docker run --rm -w /local -v ${PWD}:/local swaggerapi/swagger-codegen-cli-v3:3.0.11 generate -i openapi.yaml -l dynamic-html

The dynamic HTML was generated, but when I pull up the index.html file in the browser, it crashes the browser. I tried it in both Firefox and Chrome. I'm running Linux Mint 19.1 Tessa.

OpenAPI file: https://raw.githubusercontent.com/PresencePG/grip-server/feature/time-series/documentation/openapi.yaml?token=ABKWFWYYP4E4FNMLSAJ7U5C5OAU6I

The regular 'html' option didn't have the same issue.

Reproduce the issue with the provided docker run command and openapi.yaml, then open the generated index.html in Firefox and Chrome. Compare the dynamic-html output with the regular html output and trace the dynamic-html generator entry point. Done means the generated dynamic HTML opens without crashing either browser.
