72344 - about:blank should not resolve viewport styles or build scrollbars

Status: RESOLVED FIXED

(SeaMonkey :: General, defect)

Description

[David Hyatt]

Loading about:blank takes 4% of new window time.  Most of this time is spent 
resolving the style for the viewport and building scrollbars.  We shouldn't do 
either of these things.

sr=scc (based on the notion that |SchemeIs| will be getting better, so playing
to its strengths is wise)

I can't do this.   Editor uses about:blank.  DOM authors can start with and
augment about:blank.  It must have scrollbars.

Resolving INVALID.

Bah.

[Mike Shaver (:shaver -- probably not reading bugmail closely)]

So, for the editor case, I propose about:editor-blank.  For the DOM case, can we
detect a mutation and resolve the styles and scrollbar-fu then?

Actually, the mutation detection would help in both cases, so maybe
about:editor-blank isn't required at all.  I'll look at this.

Reopening to keep hyatt's mind on clever solutions to this problem.

Sorry, they have to be there.  The DOM thing sinks you, regardless of what
editor does.
