Testing in progress...

Thank you for the PR @Tabrisrp. During execution of test plan, with webp versions available and avif enabled, whenreoptimize with lossless compression is clicked the webp versions are deleted and avif created, While on trunk webp versions is untouched, Do we need to fix this @piotrbak ?

[piotrbak]

Yes, that sounds like a regression. @Tabrisrp the lossless/smart compression is related to the image optimization only, not the generation of webp/avif, right?

[remyperona]

The lossless level also applies to the next-gen versions, so it makes sense to delete and re-create them too

[piotrbak]

@Tabrisrp Looks like @Mai-Saad and @jeawhanlee were correct here. Currently in 2.2 we're not touching the version that's not enabled.

Is this a big effort to redo this change?

[remyperona]

It would mean to go back to the previous state, so the issue this PR is fixing would not be fixed.

Re-optimizing process is first restore the original, then optimize again with new settings, so it uses the same underlying restore methods.

@piotrbak how can we align on the expected behavior to move forward? Should we set up a quick call this afternoon or not needed?

[piotrbak]

@MathieuLamiot I think we're okay with what @Tabrisrp explained.

@Mai-Saad We'll need to update the TCs
