Google pixel 7 pro, android 13 April patches, Gboard keyboard app, Firefox for Android 112 / 113 beta: behaviour: 1) I open an app on Android (i.e. YouTube) 2) bring it to splitscreen and select Firefox as second app arranged below 3) in Firefox, I tap on the address bar 4) the keyboard appears from below, the upper app (YouTube) is halved in height (correct behaviour?) and type an URL in firefox' address bar, and press enter 4) the website loads, the keyboard slides down to be hidden again. 5) but there remains a black area at the bottom of the screen (about 1/6th of the screen height, but not as high as the keyboard was before) and the above app is still cut in half. Firefox itself looks okay and stays usable. 6) I can bring up the keyboard again by typing, the black area reappears if the keyboard is hidden again, upper app remains cut. 7) if I bring up the keyboard and then use the "hide keyboard arrow down button" in Gboard, the keyboard slides away and no black bar remains, upper app is fully visible, everything is right then. so the problem only happens if Firefox is inducing the hide keyboard command(?). - checked with different upper apps (IMs, YouTube, ...) no difference in behaviour. - tried the same with Chrome and Vivaldi browsers as "lower apps" - auto-hiding the keyboard after typing works there as intended, no remaining black area, no cut upper app. tried with Firefox in non-splitscreen mode, it works as intended there. I waited for several updates for Android, gboard and Firefox or Firefox beta, no change since like january. any idea how to solve this? thanks Seb
