John, I appreciate your openness to new browser developments, but I
find your conclusion very difficult to digest.
When basic jQuery methods are used to control visibility of an element
(and this is often outside of my control because jQuery and plugins
e.g. jqModal use them), then jQuery denies itself the option to get
the dimension of an element without flicker.
This is so because jQuery.hide() sets display to "none", basicillay
checkmating itself. So there is this conflict that on one hand you are
asking me not to use display:none which I can do by using visibility:
"hidden", but on the other hand jQuery still uses display:none
internally.
IMHO the outcome is absolutely predictable but some people get
confused with this.
The discussion in http://dev.jquery.com/ticket/5743 has turned into a
farce because not all of the involved parties seem to understand what
a testcase is. They try to neutralize the testcases by providing
workaround ideas. I have plenty of workarounds already, that's not the
problem.
I think that you would agree with me that a GUI toolkit must provide
access to dimensions of elements before showing them, without any
surprises such as flicker.
