Since the original JDK-4275046 issue is about newly entered text is made part of cell or not, it does not matter if it's in lowercase/uppercase and if such CAPS_LOCK or Shift key problem happens again, this test will not be affected.

Marked as reviewed by serb (Reviewer).

Yes this cleanup looks fine, I just would like to highlight that the actual root cause of this issue is one of:
 - Someone presses the buttons while the test is executed
 - A few tests are executed in parallel(bug in jtreg or mach5?)
 - Bug in KVM which generates this button press.
All of them are more important than the current cleanup, and I suggest investigating those possibilities on the lab_support+client_team chats
