Commit message in full
This is a performance optimization - removing
all the titles when initializing the popup extension
reduces DOM manipulation during hover, removing/reinstating the title
attribute.
When the popup extension is loaded, the default "title" behvior is unnecessary.
QA steps
- When JS is disabled a browser-based tooltip should display on hover.
- When page previews is disabled a browser-based tooltip should display on hover.
- the browser-based tooltip should not display on hover when page previews is enabled
