Public bug reported:
(this behavior is the same or at least very similar to that reported in
1878293 , (which is fixed! (thanks!!)), but now it happens in popup
windows in firefox rather than xterm. Possible regression?
The testcase below demonstrates the failure, and contains more
explanation of the issue.
Bug happens in firefox ( /usr/bin/firefox , version
85.0+build1-0ubuntu0.20.04.1 ) , but NOT in firefox installed as "sudo
snap install firefox" ( version 85.0-1 ). Also does NOT occur in
chromium-browser.
$ lsb_release -rd
Description: Ubuntu 20.04.2 LTS
Release: 20.04
Thanks as always.
Here (from <html> to </html>) is the testcase (usage notes embedded)
(also included as an attachment):
<html>
<head>
<script type="text/javascript">
function displaymessage() {
var href = "file:///dev/null" ;
var windowname = "fred_" + (new Date());
window.open(href, windowname,
'width=400,height=150,resizable=yes,scrollbars=yes');
}
</script>
<style> </style>
</head>
<body>
<form>
<input type="button" value="click here to test!"
onclick="displaymessage()" />
</form>
<p>
(Obviously, this example requires firefox and (optionally)
chromium-browser.<br>
Javascript must be enabled as well)<br>
Put this html snippet into a file named e.g. popup_test.html,<br>
then open in firefox browser, or invoke from the commandline via:<br>
% firefox popup_test.html<br>
When you click the button above, an empty, <br>
resizable popup window will be presented.<br>
Try resizing from each corner, and from each edge.<br>
The failure is this: all four corners of the popup window will move
during resizing.<br>
Expected result: at most three corners should move (when dragging a
corner of the window)<br>
or at most two (when dragging an edge of the window).<br>
(This demo works (i.e. reproduces the failure) in firefox on latest
Ubuntu 20.04)<br>
Meanwhile, the popup works fine if this example is opened in
chromium-browser<br>
(or invoked from the commandline like this):<br>
% chromium-browser popup_test.html<br>
</p>
</body>
</html>
