Hey @Telroshan,

I've rebased and added a test that fails on dev and works on the bugfix branch

[Telroshan]

Thanks!
Took the liberty to add a link to this issue (opened in the extensions repo) to your PR description for other reviewers btw, as it's directly concerned by this suggestion!

Any news on this getting merged as this fixes a problem I was having?

[1cg]

i can accept this

[RobMaskell]

I've tested this from dev and it's working for swap delay, Thanks.
@1cg There seems to be another PR raised recently that fixes this issue too (and others, like view transitions)
