bug or feature?

[QZMTCH]

Because the Alt key dismiss the context menu by default, it is impossible to make the menu pop up by pressing Alt+Right-Click, so this bug has no effect in most cases.

but in js there is such an event, and in other browsers it can be used

now there are many sites where online tools are used to edit something, and there can be combinations of alt with the right button (like online photoshop)
