no context menu on input fields

[r10s]

normally, a right-click in an input field shows a system-context-menu with cut/copy/paste and maybe other system-special things (spell correction etc).

currently, this system-context-menu does not appear - but also, no replacement that may be done by chrome appears.

not sure, if the system-context-menu is doable, however, having a menu with at least "paste" is expected in many workflows. i just checked signal, who are also using electron afaik, and there is a context menu.

maybe there is just a return value from some event handler wrong? so that passing the click to the default handler is skipped?

electron doesn't have one.

looks like maybe electron has a way to use the system menu: https://www.electronjs.org/docs/tutorial/spellchecker, so we could have an option that it used instead of our implementation if available... (we can think about that after upgrading electron, but that's a sidequest this only affects how the context menu will look, probably)

What we need is an catch-all on contextmenu that triggers on input fields and only triggers if the event wasn't handled before. I would appreciate if we find a way for that without calling event.preventDefault() and event.stopPropagation.
