css3 test makes page hang

[StevanWhite]

This very nice on-line CSS3 test doesn't do well on Otter 1.0.03 (on Manjaro Linux)

https://css3test.com/

1. After the page (at least partially) loads, the tab becomes unresponsive, and scrolling stops working. Closing the tab from the File menu then causes the browser to crash.

2. The page reports 48% support for CSS3. (As the page says, this is just the portion of CSS the browser recognizes, not what it correctly implements.) Gecko is at 89%, and Blink at 90%.

Gecko is at 89%, and Blink at 90%.

A bit besides the point (that'd be the freezing) but I see significantly lower values (63 % and 70 %)?

This is one of those situations where switching between QtWebKit and QtWebEngine (and different versions thereof) can make a difference btw. :-)

About the support values: I see those on the Manjaro distro installations of Firefox and Chromium.
Now, Manjaro is an Arch Linux derivative, and tends to use the latest stable releases of stuff.
I tried the same page on Android, where I see values like yours, for FireFox and Chrome.

I'm glad to hear that a change of rendering libraries could boost the standards compliance.

But as you emphasized, the main thing is this hang. (See also my report about a similar issue, loading multiple MP2 videos.)
