TextView stops being responsive after application is sent to the background

Describe the bug When the application’s window stops being active by sending it to the background using Alt + Tab (not with the mouse) and then it is brought to the foreground again, a TextView component stops being responsive to many keyboard inputs. Even though, you can type in new characters, you cannot move the cursor using the keyboard arrows or change a line with enter or delete characters with backspace.

To Reproduce Steps to reproduce the behavior:

1. Use a multi-line TextView in an application, type in characters and move around the cursor freely using the keyboard arrow keys.
2. Change the active window by using Alt + Tab. This of course assumes having at least one other application open in your OS.
3. Re-activate the application’s window by using Alt + Tab again.
4. Notice that you cannot move the cursor with the keyboard anymore. Pressing enter or backspace also has no effect, but you can type in new characters.

Expected behavior The TextView’s functionality should not change when the application loses focus at some point in time.

Desktop (please complete the following information):

• OS: Windows

Additional context I noticed this behavior in older versions too, it’s not new.

Cool. So just the other one wasn’t fixed.
