Hover on keyboard modifier should trigger instantly

[benvillalobos]

#274001 added support for a new setting to only allow hovers when a keyboard modifier is held.

The issue is:

• Hover over something (no hover comes up)
• Press ctrl or alt
• 🐛 See that no hover comes up UNLESS you move the mouse

This looks good! One thing I noticed though is that when the setting is onModifierKeyPressed and I press option the hover does not appear immediately, it only appears after I move the mouse again so the calculation retriggers. I think if we implement this it would make sense to add code to immediately trigger the hover (after a delay potentially) without having to move the mouse again.
