When a web page is rendered in webKit and inspect32 tool is invoked, title attribute is not properly populated for Image tags.
Ideally, it should be set with the alternate text if any. (This behavior is observed in Firefox 184.108.40.206).
This patch is already approved by Jon as a part of bug 20013. I am logging this bug to track this specific issue separately.
