chatview: dropdown menu does not always appear when clicking the ellipsis
Sometimes the ellipsis does not trigger the delete dropdown menu when clicked.
How to reproduce: Does not always happen, pretty much non-deterministic. Certain images are especially prone to trigger this bug when present in the chatview, but still it's hard to tell what happens exactly.
My best guess is that WebKit can't handle the dropdown menu in all cases because it's a bit hacky, and we'll have to rewrite it with less js.
