Do not pop up emoji tabbed panel and media menu on mouse over

[mymedia2]

I suggest to not spawn popups on simple mouse over. When a user just moves a mouse, they does not expect to raise any windows. In Telegram, this may lead to really annoying missclicking when the user wishes to send a text or choose a message for reply.

I was going to leave activation a third panel by double left click on emoji button. Although, I did not find an addDoubleClickHandler or similar in Ui::AbstractButton. So for now I use single right click to toggle the third panel in history widget. You may consider this as a start approach.

I really don't want to dishonor the work you did for this PR, but I actually really like the existing mouseover feature and would dislike if it was changed. I can't remember ever misclicking due to this feature.

Just wanted to link a specific issue discussion regarding this:

Sorry, it works as it is supposed to.

@john-preston does it mean there are no plans to implement at least some improvement like popup delay (even ~200ms would be enough)?

Right now it's like you have to play a cursor maze game if you want to touch anything in the right bottom corner of UI and not trigger emoji panel.

@reallyuniquename I really cannot understand your cursor maze game... Are you perhaps a touchpad user with a very bad touchpad? I never had any problems with the popup myself, so I am curious why it seems to be such a problem for some people.

@magnus-gross it really depends on your workflow. I mainly have two issues. If you run Telegram window maximized system toolbars happen to be right under emoji button, it's almost pixel perfect, I kid you not. I trigger emoji popup like 90% of the time when I touch anything in that corner. Likewise when you finish formatting Telegram message using mouse the shortest cursor path to the Send button goes right through emoji button.

Maximized Telegram window have the ability to put the emoji panel at the right side of the window -- click the emoji button on maximized -- this will solve the problem, though I doubt people are using maximized window all the time.

I think the issue is with people who uses the smallest Telegram window size, the popup will happen if you hover around the bottom right corner.

Double it.
The option to show emoji popup only after button click wolud be brilliant.
