Does !element.setText(text) replace the text? It's unclear why all this is necessary.

[mykola-mokhnach]

yes, setText does replace the current text. This just optmizes the logic if we know the content should be replaced, so we don't perform unnecessary calls to accessibility methods.

This is way better than before.
When replacing, the element does not get cleared, and this allows for locators that have a condition on the text.
