Fixes #28997.
This is a much more extensive than I intended fix for #28997.
The main point of #28997 was that
scroll
is an inappropriate event to choose, because it's not cancellable (as the page itself already says). But also, the example showed a lot of feature-detection stuff, which I don't think is very relevant any more, and didn't show anything about the actual effect of the option.So I have:
passive
on awheel
eventAll that is in commit 9b37e12.
Then I realized that this page contains two H2 sections, "Usage notes" and "Other notes", which seemed ridiculous, so I merged them in commit d2e114b. So that commit is really just moving stuff around.
