JetBrains: Remove second popover show call

Created by: philipp-spiess

Fixes #35922 (closed)

The popover fix that I've added contained an unnecessary call to showInFocusCenter which is not necessary as the popover is already aligned because of the first time it is shown. The workaround remains in tact

Test plan

I manually tested this by opening the app on macOS and verified that no more error is thrown neither on the first opening nor on a later one:
