Textarea form element does not support #pattern

Does pattern work on textarea elements? https://developer.mozilla.org/en-US/docs/Web/HTML/Attributes/pattern says "The pattern attribute is an attribute of the text, tel, email, url, password, and search input types".

Thanks @cilefen

Yes i think you are correct.

Actually even the w3c also links points this out

Note: The pattern attribute works with the following input types: text, date, search, url, tel, email, and password.

I guess that would explain why text area was omitted from the drupal fapi implmentatiion.

That said, apparently, it is also possible to implement pattern on text area using custom code:

This could be useful in some situations where text input is longer than can be fitted into a text input.
