Press Keys causes two key ups for selenium special keys

[MrBIN89]

Steps to reproduce the issue

Press Keys keyword execution with special selenium keys, for example Press Keys css:locator BACKSPACE, brings two _keyup events unexpectedly. That causes two letters removal instead of one in my case.

Though in case the selenium key code is used there is no event duplicates, works like a charm

Expected behavior and actual behavior

I was expecting that the Press Keys should work consistently for both scenarios, send key_down and key_up for once only:

1. Press Keys css:locator BACKSPACE
2. Press Keys css:locator \ue003
