Fix T94316: Asset catalog tree scrolls away when renaming a catalog

The activation of the text button is a bit special, since it happens during
drawing, the layout isn't computed yet then. Comparable cases where the button
is added on top don't use the layout system, so this didn't become an issue
until now. Trigger a delayed call to `UI_but_ensure_in_view()`.
