617034 - Better define the interaction between innerWidth/Height and the meta viewport tag

Status: RESOLVED INCOMPLETE

(Core :: Layout, defect)

Description

[Wesley Johnston (:wesj)]

Spun off from Bug 602580. There we changed (are changing) innerWidth and innerHeight to return and set the CSS Viewport is a custom CSS Viewport is in use. However, there don't seem to be any strict definitions of how this should be done. Especially in the case of setting innerWidth and innerHeight, the interaction between setting innerHeight/Width in js and using the meta viewport tag should be defined. Which one takes precedence?

I wonder if this is related to this Web Compat issue.

This is a very old issue and doesn't look actionable any more.
