Hello, this is my first time filling a bug.

I noticed a problem when I call function to show the on-screen keyboard and hide it again, I didn't receive "Back" button key event (keyup/down) and the app exit instead (but not crash as I receive the quit event). If I set SDL_ANDROID_TRAP_BACK_BUTTON hint, the app didn't exit but I didn't receive "Back" button key event either.

This is similar to # 4702 but the difference is that I only encounter this issue AFTER calling "SDL_StartTextInput". This means that if I didn't call this function, I receive "Back" button key event correctly, even without the hint described above. As I'm testing this with changeset 472db3f71645 (tip as of writing), this means the fix there isn't effective to me.

My device is Mi A1 running Android 9 unrooted. I can add traces to the SDL code if needed.

I think this is fixed with:

When the text input is hidden, we need to set back the focus on mSurface
Please let me know

Didn't know the fix is that simple. Thanks, it now properly capture "Back" button as escape again.
