69979 - long wait for ReplaceComponentSelect()

Status: VERIFIED DUPLICATE of bug 27233

(Core :: DOM: Core & HTML, defect)

Description

[C.R. Labombard]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; WinNT4.0; en-US; 0.8) Gecko/20010222
BuildID:    2001022209

I noticed an inordinate wait when the Component option list changes on the
submit-a-bug page at Bugzilla.

Reproducible: Always
Steps to Reproduce:
Just choose a selection from the Product field.

Actual Results:  The field change in Components will take several seconds and
during that wait the browser locks up.  Afterwards, everything returns to normal.

From http://www.mozilla.org/quality/help/bugreport.js

After the selection is made, UpdateComponentList() is called which should then
call ReplaceComponentSelect().  ReplaceComponentSelect() apparently triggers the
delay.  The CPU usage meter in NT's taskbar goes all the way to 100% during this
delay.  I didn't see any problem with the function itself, so the JavaScript
engine was what came to mind.

Expected Results:  The transition should have been done in an eye-blink.

Keep rockin' --both my wife and I like Mozilla!
