text.module missing text_library_info() - does not explicitly declare js dependencies

Inline with #1737148: Explicitly declare all JS dependencies, don't use drupal_add_js
File should be declared as a library with dependency on jquery and attached using library, instead of js.

Tested manually, looks good to me

Screenshots

Note this will conflict with #1704864: Add a "Required" and "Show by default" option for "Text area with a summary" field/widget. so one of the two will need a re-roll. Probably better to make it this one as the other is a larger patch.

@nod_ pointed out we need the jquery.once dependency too

and also, we don't need the jquery.form dependency

it's jquery.once the dependency name, not drupal.once :)

Good to go

Committed and pushed to 8.x, thanks!

However, I'm wondering if we need to put some babysitting code in here. This is at least the 3rd or 4th time we've caught one of these. If hook_library_info() is actually supposed to be required, it seems like we ought to throw a notice or something when a library is accessed out of band? Could we open up a follow-up (if it doesn't already exist) to discuss?

Follow up is #1890912: Consider possibility of throwing a warning when js is attached without a library (and assoc dependency chain).
