Morphdom throw errors on page update when using petite-vue

[stormitornado]

Hi! Maybe it'll duplicate some issues, but I think this one can be solved. I use Petite-Vue framework on my pages, and it provides some non-standart attributes like @vue:mounted and @vue:unmounted. On page update I get this error in console:

[11ty][18:11:13.032 UTC] Morphdom error DOMException: Failed to execute 'setAttribute' on 'Element': '@vue:mounted' is not a valid attribute name.

Is it possible to fix attribute parsing, and not just switch off diff-updates ?
