How to ignore arguments to non-standard tags?

I'm using tsdoc and its eslint plugin with great satisfaction.
Now, to document *.vue files (compose API + script setup + typescript + vite), I started using
vue-docgen-cli (I had problems installing vue-styleguidist).
This tool, to document emits, uses a non standard tag @arg with a complex argument. Here is an example:

const emit = defineEmits([
  /**
   * Changed when the dialog visibility changes
   * @arg {boolean} visibility - Dialog is visible
   */
  "update:modelValue"
]);

Rightly eslint complains about the braces:

tsdoc-malformed-inline-tag: Expecting a TSDoc tag starting with "{@"
tsdoc-escape-right-brace: The "}" character should be escaped using a backslash to avoid
    confusion with a TSDoc inline tag

Tsdoc.json is (simplified):

{
  "$schema": "https://developer.microsoft.com/json-schemas/tsdoc/v0/tsdoc.schema.json",
     "tagDefinitions": [
        {
            "tagName": "@arg",
            "syntaxKind": "block"
        }
    ],
    "supportForTags": {
        "@arg": true
    }
}

Changing braces or escaping them makes the argument not recognized by vue-docgen. Is there a way to make tsdoc ignore or not check a block tag? Or the only way is to complain with vue-docgen developers?
Thanks for enlighten me!

Start with the reported tsdoc.json tagDefinitions and supportForTags settings, then trace the diagnostics tsdoc-malformed-inline-tag and tsdoc-escape-right-brace for the @arg example. Done means determining whether TSDoc can accept or ignore this block-tag argument syntax without breaking vue-docgen, or documenting that the compatibility change belongs in vue-docgen.
