Touch screen input not registered on some title bars

Fedora generally appears to support touch screen input, but for some windows basic things aren’t working.

For example I can use touch input just fine in Firefox, but I can’t double tap the title bar to maximize it and I can’t drag the window from the title bar.
I can however resize the window by dragging on any corner or edge of the window.

There also seem to be some other issues in Firefox, e.g. context menus can’t be closed.

Am I missing something? I couldn’t find anything in the gnome settings to improve touch support.
