Variable inside html isn't replaced

[Zerotask]

Describe the bug

{
    "registerHere": "Or <a href='{url}'>register here</a>"
}

<p>{@html $_('registerHere', { values: { url: '/register'}})}</p>

Will produce:

<p>Or <a href="{url}">register here</a></p>

Without the @html it's the same.
If I place the {url} variable outside the html code, it will be replaced correctly.

Expected behavior

<p>Or <a href="/register">register here</a></p>

The dependency intl-messageformat parses tags, see this section of the docs.

You have to use a very strict format so it does not just throw SyntaxError: INVALID_TAG, i.e. double quotes for attribute values:
'Or <a href="{url}">register here</a>'
