1759962 - Mispositioned context menus in RDM with override DPI

Status: RESOLVED FIXED

(DevTools :: Responsive Design Mode, defect)

Description

[Emilio Cobos Álvarez (:emilio)]

I suspect this is due to bug 1753836.

STR:

• Open RDM.
• Set the DPR to a value that doesn't match your native DPR.
• Right-click anywhere on the page.

AR:

• Context menu is mispositioned.

ER:

• Context menu works as usual.

Attachment: Bug 1759962 - Don't return the DPI override in devicePixelRatio to privileged code. r=nchevobbe,mtigley

Chrome code should be able to rely on CSS pixel * devicePixelRatio =
device pixel.

Chrome code that cares about the override should use
BrowsingContext.overrideDPPX. We were exposing the no-override value in
WindowUtils but that's unneeded now.
