Move visible logic inside each button
Move click functionality inside each button
Extract getButtons function from Toolbox components to functions file
- clicking toolbox button was keeping focus on toolbox even after mouse move(as focus would only be changed when clicking on some other element), so .toolbox-content-items:focus-within selector was returning a value even when mouse was moved from toolbox
- .filmstrip:focus-within did not seem to ever activate, I replaced with :hover since the intent was probably to keep the toolbox open while filmstrip is hovered
