On links, as well as elements styled "cursor: pointer", the tooltip's initial position is such that the first few characters cannot be read due to the hand cursor appearing over it. Occurs with the system provided "extra-large" pointer scheme on Windows.

Reproducible: Always

Steps to Reproduce:
1. Change pointers to Windows Aero (Extra Large)
2. Find a link (or element with style "cursor: pointer") with a title attribute
3. Hover over it until the tooltip appears
Actual Results:  
The hand cursor covers the beginning of the tooltip

Expected Results:  
The tooltip should be positioned taking into account the size of the current cursor.

Extra Large pointer scheme should be selected on Windows

This Bug still exists with Fx7.0a1.

The position is hardcoded here¹ but it should depend on the size of the mouse pointer.

Seems to be a problem on FFx 16.0.2 under KDE as well. Can't read the first several characters of tooltips because of this.

This is currently considered to be normal behavior for most browsers and OSes, but fixing it would be an improvement.

I'm annoyed by this every day. Using KDE in Linux. I have to put a large cursor because in some circumstances I have trouble finding it with my screen setup.

Possible duplicate of bug 248718.

Whichever way it is, this is probably a bigger deal on Windows now because now you can pick even larger cursors—the old sizes of normal, large and extra large have been replaced by the numbers 1, 2 and 3, and the scale now goes up to 15, which is more than four times the size of the old Extra Large. Vision-impaired people will often choose quite a large cursor, and they basically can’t see half the tooltips. I’m not even vision impaired, I just like to be able to find the cursor, but tooltip positioning is making it hard for me to have it even at size 3, let alone 4 as I’d like. For example, at 4, the first three letters of the first two lines of a tooltip are completely obscured.
