Hi @almendron - thanks for the bug report.

Did you notice any effect of the missing webp extension in each of these cases? I agree thee likely need updating, however it would be good to understand what each does so we can document and test that the change fixes an issue.

Rest of cases: not verified.

I believe the usage in wp-includes/js/dist/block-editor.js comes from Gutenberg.

I opened this PR to updates usages in Gutenberg (although I don't know exactly how these are used, I assume webp should be added): ​https://github.com/WordPress/gutenberg/pull/36361

This is fixed upstream in ​https://github.com/WordPress/gutenberg/pull/36361 which I just merged. Marking this ticket as resolved.

@almendron let me know if you still see this issue anywhere, thanks again for raising.
