Change "Activate Mode for editing render region button" behaivior

Hi, I simply dont understand why we need this button for this purpose.

What it only does is activate the edition for the regions.

I think that this button should enable/disable all render regions. For me its not logicall that this only enables the edition.

Regions are still active, in order to disabling regions (which is more important rather than activate the edition) we need to click on the arrow and then click "disable all".

For me its confusing, editing render regions should always be active, maybe lock them with an option in the arrow.
