Pale Moon locks up on Virgin Money site

When I attempt to view the Virgin Money site info on their ISAs pale moon locks up completely. I have to kill it with the task manager and remove the VM site from the list of restarted web pages to clear the problem.
The difficult url is
https://uk.virginmoney.com/savings/prod ... nformation
I cannot provide any debugging info as PM is completely unresponsive.
NB - You do not have to have a Virgin Money account to access this page.
Forgot to say this was on Win 10 with the latest PM build

Yep, I'm seeing that happen too. Pale Moon's UI becomes unresponsive, it pegs a core at 100% and then just sits there slowly eating up memory. PM 32.0.0 on Linux (KDE Neon).

Probably a script recursive issue (maybe another case of mutationobservers?)

Not sure what "mutationobservers" is all about. Does that mean it is fixable?
I managed to get a little bit of debug info by starting the debugger tools before going to the problem site. Unfortunately the debugwindow is also frozen so I can't get the info to paste here.
There is one red-flagged message about Content Security Policy "Ignoring x-frame options" because of fame-ancestors directive and one warning that container.buildInfo.environment is deprecated.
Got to kill it now as Palemoon memory usage has almost reached 10GB

Yes it's fixable, but it's not an easy fix so the UXP issue is still open. Look at
UXP #1808 for details.

They do know we have
sticky CSS keywords for that, right? It'd be a lot more performant as well not doing it in JS.

That looks to work.
In uBlock Origin -> Dashboard->Filters, (& not being familiar with this stuff) I added:
Code: Select all
