215295 - inline applets do not scroll (or tab) off-screen correctly

Status: VERIFIED DUPLICATE of bug 162134

(Core Graveyard :: Java: OJI, defect)

Description

[Craig Reynolds]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.4) Gecko/20030624
Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.4) Gecko/20030624

This is in Mozilla 1.4 on Mac OS X.  I do not see it with 1.4rc1 on Linux.

I first noticed this on one of my pages (http://www.red3d.com/cwr/boids/ -- but
I list http://www.mrl.nyu.edu/~perlin/rosie in the URL field as an example by
someone more likely to know what he is doing).  When the page is first loaded
the applet (near the top) is displayed normally.  When I scroll down (using Page
Down key, down arrow key or scroll bar) does not stay fixed in page space.  It
seems reluctant to leave the browser pane's viewport.  

If I use the down arrow or the scroll bar's down button, the applet will mostly
scroll off the page, leaving a small strip (less than the height of one line of
body text) of its bottom hanging at the top of the browser pane.  If I use the
page down key, or click on the bottom of the scroll bar, or switch to another
tab (as in tabbed browsing): the applet appears to stay at the same screen
position while the page contents at that screen location change.  (For example,
when I tab from my boids page to this bugzilla report form, I get the boids
applet running happily overlaid on the bug report form.)

Reproducible: Always

Steps to Reproduce:
1. open http://www.red3d.com/cwr/boids/
2. press Down Arrow key until applet's location is scrolled off top of page
Actual Results:  
a bit of the applet remains, misplaced, at the top of the browser window

Expected Results:  
not drawn the misplaced portion of the applet

can you check bug 162134 and dupe it if appropriate ?

Comment 2

[Craig Reynolds]

I'm not sure if that comment was directed to me.  In case it was:

(a) yes, my bug reports appears to be a duplicate of bug 162134
(b) may I suggest that they keyword "applet" be added to 162134?
    That was why I didn't find it when searching this morning

Cheers,
Craig

(b) I'm unsure as it'd generate lots of bugmail (given the number of people who
are CC'd). :/
