Demo doesn't work

[jespertheend]

When I run the steps at the bottom of readme.md and go to http:https://localhost:5000/demo/, the ripple effect doesn't work for any browser except for Chrome.
https://googlechromelabs.github.io/css-paint-polyfill/ still seems to be working in Safari and FireFox though.

I checked the different releases on Firefox 89. 3.1.0 works well, but not 3.1.1.
The change in maybeUpdateElement() broke it:

Ah that explains why https://googlechromelabs.github.io/css-paint-polyfill/ is still working on Firefox. I guess it's using an old version.

Fix released as 3.3.0 - thanks!
