1342555 - Tooltips appear in the wrong place when in Responsive Design Mode

Status: NEW

(DevTools :: Responsive Design Mode, defect, P2)

Description

Attachment: Tooltip for image appears at the far left

When in RDM-V2, hovering over an element with a title will show the tooltip far away from the element. The narrower the viewport preview, the further away it is from where it should be.

(Clearing priority for now, so I can take a look at this during the next triage.)

I can confirm the tooltip in the example is oddly placed.

In older versions the responsive view used to be aligned on the left of the Firefox window, then it moved to the center, now in version 53.0 it seems to be on the left again. From my observation the tooltip hadn't migrated correctly to the center in between.

Recent observation:
Version 52.x.x: responsive view was centered, tooltip was too far to the left (outside of responsive view).
Version 53.0: responsive view is back to the left, tooltip placed correctly.

If it's back to the left, you're probably seeing the old RDM.  The new RDM is currently only used when e10s / multi-process mode is enabled.

It reverted back on its own. e10s / multi-process defaults must have changed between versions...
