[Mobile] Mobile UI cannot insert media from page media

In order to get to the media tooltip to insert, I have to hold press and that makes me loose my cursor in the textarea causing the media link never able to be inserted.

Samsung Galaxy S22 Ultra - Chrome Browser

Reproduce the media insertion flow on a Samsung Galaxy S22 Ultra using Chrome, focusing on the media tooltip, long-press behavior, and textarea cursor. Trace the mobile UI entry point for inserting page media; done means selecting media inserts its link without losing the textarea cursor.
