using on-screen-keyboard to set the resolution when resizing

[chri2]

On Librem5 using PureOS Byzantium (Debian Bullseye), Phoc/Phosh, using ImageRoll 2.1.0 (flatpak from flathub):

• load a picture
• click on the symbol to resize it
• the dialogue shows to enter the new size
  • tapping the increase/decrease arrows just works as expected
  • opening the keyboard closes the resize dialogue
  • reopening the resize dialogue with the keyboard already opened closes the dialogue when anything on the osk keyboard is tapped

Expected behaviour: it should be possible to open the keyboard to enter a dimension for resizing by using the on-screen-keyboard (just like when using a real keyboard connected to the same device through usb-c).
