[Laszlo-dev] Need input on [#LPP-8375] onmouseout even on HTML component is firing onmouseover, not onmouseout - OpenLaszlo Jira

[Max Carlson]

Yes, it makes sense.  See lps/components/extensions/html.lzx for the 
handoff - the view:

     LzMouseKernel.disableMouseTemporarily();

Maybe that call should prevent the next onmouseout event from being sent?

The next thing that happens is the mouse leaves the iframe and mouses 
over the canvas container div (see the LzSprite constructor for the 
canvas - isroot == true).  If the mouse goes over an element inside the 
app, LzMouseKernel.__resetMouse() is called to restore clickability.

You might try running with backtrace on to see where the spurious 
onmouseover event is being fired from...
