Mouse clicking doesn't work for A-frame examples

I’ve been doing various examples that have mouse events, cursors, etc and I can’t get the clicking to work. The cube often increases in size even without mouse enter but never reverts back with mouse exit. Any ideas? Thanks.

Could you share you code or project?

this one doesn’t seem to work either mouse enter/exit https://glitch.com/~temporal-mixolydian-havarti
no audio either

this is when the view is next to the code on right side of screen.
