1. When editing code from the ‘hover’ window and pressing ESC, changes are still visible in source view. Why?

ESCAPE closes the hover window and commits your changes. This is by design.
This functionality was first implemented in Antegram. In Antegram there is no source view and we always edit from the outline view. There has to be a fast, easy to reach key allowing closing the hover window. ESCAPE and SPACE are probably the fastest keys on a standard keyboard, and obviously SPACE can’t be used in this case.
