Wrong tooltip position in Firefox/Safari when assigned to element not wholly visible.
I was testing the tooltip assigned to a text cropped with ellipsis. On Chrome it is positioned nicely. On Firefox and Safari however, its position is calculated wrong. This when effect="solid" and placement="top|bottom"
Correct position (Chrome)

Wrong position (Firefox, Safari)

I have discovered that the reason for that is how browsers understand the Element.getBoundingClientRect().width. In Chrome is is the portion of width visible to the user. In Firefox / Safari is the total width, including the hidden part.

Firefox / Safari

Obviously this is a purely browser problem. It should to be fixed based on the HTML tag I guess.
Any updates on that?
We're targeting Safari (many people are), so we must fix this.
Does anybody have plans to work on this, or will it not work in Safari? If so, why?
