[BUG] Onscreen Keyboard not showing up on Plasma Mobile, hardware keyboard works

Description

Whenever I open Axolotl on my PinePhone running Manjaro with PasmaMobile, I can't type anything because the onscreen keyboard doesn't show up. I'm not really sure if this is a problem with Axolotl or with Plasma Mobile, but I only experience this issue with Axolotl. When I plug in a USB keyboard, it works fine and I can type in every textfield.

Steps to Reproduce

1. Start Axolotl (AUR version)
2. Try to type in something in any textfield

Expected behavior: Onscreen keyboard shows up and I can type in something (for example my phone number on the registration page)

Actual behavior: No keyboard shows up and therefore I can't type in anything, it only works when I plug in a hardwa[What actually happens]re keyboard.

Versions

Axolotl Beta 1.0.4

Device

Pine64 PinePhone (Beta Edition)
running ManjaroARM Plasma Mobile

@nsc-nis not sure if the others need the log... but as far as I remember, the log file is only present as long as the app is running.

Thanks for posting the issue. From my point of view, it's an Electron thing - I have the same behaviour with Telegram Desktop (Electron app) on Mobian@Pinephone.
And when using the daemonised server setup (cog or Firefox as browsers), the issue is not present.

So @nuehm-arno there is nothing I or you can do to fix this issue?
