Don't reset wxPGProperty editor if focus is switched between its components

As long as focus is being switched only between subcontrols of the active editor the state of the edited wxPGProperty remains unchanged and there is no need to explicitly reset the editor.
Unwanted editor resets could happen if such internal focus changes would be captured in EVT_IDLE handler.

Closes #18162.
