Are there disadvantages to intercepting click and hover events when menu is open?
When a menu (application menu or context menu) is open some applications intercept all clicks and mouse hover events, while others do not.
For example if you open a website on Chrome (on Ubuntu - I am not sure if the behaviour varies between platforms) and then open the browser's native context menu, you cannot click on any link without first closing the menu, while hovering over links/buttons will not send mouseover events to them while the menu is open. To the contrary, in Firefox you can open a context menu and elements in the background will still receive the "hover" style/signal, and if you open hamburger menu even clicks will work.
Is one of the approach more user-friendly?
