[codokie]

fixes #616

[Helium314]

Thanks!

[Uranusek]

Thanks for fixing this. Unfortunately, there is still a problem with items temporarily disappearing from the clipboard after changing the keyboard.

To reproduce

1. Change the keyboard
2. Return to HeliBoard
3. Open the clipboard
4. Wait a moment
5. See items disappeared (even pinned)

The items appear when you reopen the clipboard and the problem no longer occurs. Well, unless you change the keyboard again.

First the compiled debug APK, and now version 1.3 and the problem still occurs.

could you open an issue for it please with a video reproducing the bug?

Sure, although I already reported it #616 There is also a video showing this bug. If necessary, I will open a new issue.

[codokie]

Ah I did not notice the video, for some reason Github collapsed it
I have found what is causing this issue and will open a PR shortly
you could reopen #616 since one of the issues there has not been fixed yet (maybe change the title if you do)

[Uranusek]

I can't find an option to reopen the issue. Maybe only @Helium314 can do it.
