window.outerHeight on Mobile

[bramus]

window.outerHeight is specced as follows:

The outerHeight attribute must return the height of the client window. If there is no client window this attribute must return zero.

There’s a few interesting things going on with on Mobile, as found through testing

Discussed during #20.

Looks like a bug in browsers,. Additionally, the term “client window” in the definition is not defined by itself.

There’s an existing bug for Firefox on Android: https://bugzilla.mozilla.org/show_bug.cgi?id=712225

Emilio notes that the value is sometimes spoofed for security reasons.

API also seems low-prio / not used often.

• @dcrousso Can we discuss again? What did we resolve on?
• @emilio Spec needs update
• @bramus What about the spoofed value?
• @emilio Tor Browser defo wants this. We might not need to account for that in the spec
• @bramus Or maybe a small line that says UAs might not return a proper value for tracking reasons
• @skobes What about screen size?
• @emilio Tor also spoofs that.
• @skobes Does the spec have about that?
• @emilio Don’t think so.
• @emilio Sometimes they (screen, inner, outer) are all the same – e.g. Tor
• @emilio A small note in the spec would be fine
