It's working fine from what I tested with the scratch project with the latest Svelte 5 version.
Btw could you share your rendered HTML file?
Maybe some of the attributes are removed by the 'html-minifier-terser`.
You could also disable the config https://github.com/terser/html-minifier-terser#options-quick-reference.

Also, there are defaults here that could break the HTML attributes

sveltekit-html-minifier/index.js

Line 19 in 3ea53e2

minifierOptions: {

That sounds like you're removing whitespace and/or comments via the minifier, which Svelte is sensitive to. Try turning those parts off.

For me it was collapseWhitespace.

It seems many people have this issue, so I decided to remove the collapse whitespace by default.

It will fixed by v1.0.4
