A performance profile can not be recorded, since the system freezes/restarts

I can reproduce the huge memory usage on Nightly139.0a1 Windows11. And I also could not capture the performance log.
Memory usage seems to be getting worse with each new version. This was especially noticeable for the following

#1 Regression window(the memory issue was first seen):

#2 Regression window(It got so much worse.):

ni? on Glenn for one of the regressions, maybe this gives us an idea.

[Dennis Schubert [:denschub]]

Jeff, since Glenn is on PTO, maybe you can move this forward

My guess is that this is the lottie <svg> animation. It has a bunch of filters and probably having a bad interaction with SVG blob image code.

Attachment: Render task graph

The render task graph shows thousands of 1080x1080 render tasks. It looks like we are poorly restricting the bounds or resolution of the render tasks for most of the SVG nodes on this page since we have a lot of tasks that look like this:

[...] -> [SVGFENode 1080x1080] -> [Picture 19x16] -> [...]

Ashely, can you take a look to see if you can figure out why the render tasks are so large?
