User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:75.0) Gecko/20100101 Firefox/75.0

Steps to reproduce:

tried to use the poll widget embedded into many articles on tagesspiegel.de using firefox preview and firefox beta for android on my sony xperia xz1 compact (Snapdragon 835 based).

The link was suggested by firefox pocket.

Actual results:

the poll widget renders extremly slowly - leading to wrong input most of the time.
My phone is a yeasterday's flagship phone, so I guess on smartphones with e.g only little cores it will not work at all.

Please see https://www.youtube.com/watch?v=cTu8jQWcTZE&feature=youtu.be for a screencast.

With google chrome it reacts as expected.

Expected results:

the poll widget should work as smooth as with google chrome when using firefox preview.

Real bug, assessed as P3. Note that the original URL has changed, but this website construction idiom is elsewhere and in common use.
