Tooltips remain visible when launching external window

[Bodekaer]

Let's imagine you have a link that launches a URL in new external window/browser.
If you click that _blank url link right before the tooltip starts to fade in - then it doesn't disappear again, because the new popup window (that's launched by the url click in fullscreen), now has the mouse focus.

Therefore the tooltip for some reason doesn't register the MouseLeave event, that normally triggers the tooltip to disappear.

Hope this is enough to replicate it.
Simply create a link that open an external popup window (fullscreen), and then try a few times to click the link, right before the tooltip fade-in animation gets to finish.

This is actually causing quite an annoyance for our users, so I hope it can be fixed.

A quick and dirty hack would be to call _browserControl.SetTooltipText(null) from within ClientAdapter::OnBeforePopup

Somewhere in this method, https://github.com/cefsharp/CefSharp/blob/master/CefSharp.Core/Internals/ClientAdapter.cpp#L34

Since we don't currently have tooltips with WinForms I guess this can be marked as "wpf"

@amaitland, would there be a way for me to clear the tooltip from the ManagedCefBrowserAdapter?
I don't seem to be able to find it.

Basically, I would like to clear the tooltip on MouseLeave, e.g. here:
https://github.com/cefsharp/CefSharp/blob/master/CefSharp.Core/ManagedCefBrowserAdapter.h#L171

With something like:
if (mouseLeave == true) { clearTooltip(); }

The reason I suggest this, is that the ClientAdapter seems to have no reference to mouse events (but does have keyboard events though).
I think the best implementation here would be to hide the tooltip on MouseLeave.

@amaitland From within ManagedCefBrowserAdapter you have access to IWebBrowserInternal^ _webBrowserInternal so you should be able to call _webBrowserInternal.SetTooltipText(null);

Will that work?

[Bodekaer]

Worked perfectly.

Changes merged so closing this one.
