HTML is stripped on front from titles but not in customizer

[karmatosed]

I was working with the audio widget and noticed that the HTML tags are stripped from the front, yet show in customizer.

The output is this:

I would suggest either add information to say this happens or strip on save.

I am only getting this behavior if I click out of the Audio, Video, or Image widget immediately after entering a tag into the title field. If I wait for the update-widget spinner to finish and then click out, it doesn't clear like it does for other widgets. This is due to the new media widgets only using the input event instead of also including the change event for when to handle updates.

I think all that may be required here is to add change to the events that are attached to the title field.

In 40785:

Widgets: Ensure title field for media widget will update with sanitized value after change event in addition to input event.

Aligns behavior of field with Text widget and other widgets whereby the server-sanitized title (via the widget-update request) is supplied into the field after the change event.
