Cannot open context menu on touchscreen

[julianfairfax]

As described in the title, tested on the latest Flatpak version.

I tested this on my PineTab2. Neither a single press, double press, or longpress would open the context menu. The touchpad works.

There isn't a context menu. If you are able to select text you should see a menu upon selection (for touchscreen selection, see #207).

That does not happen on touchscreens. Text selection is, while not a great experience, somewhat possible via double and triple tap. But the selection menu does not pop up.

Does the menu pop up if you tap on the selected text?

[julianfairfax]

No, it just selects it

[johnfactotum]

I mean if you select some text with double tap, and then tapping on the selected text again.

If you do this too quickly it would be treated as a triple tap. So you need to wait long enough before tapping the third time, which should deselect the text (which is the normal behavior). But in Foliate, in addition to the text being deselected, it would also open the selection menu if it's not already opened (which is actually a bug).

If that does not happen, I would guess that there might be some GTK bug that prevents the popover from showing.

That deselects it.
