The muted attribute does not render in the video tag Svelte-5

[tbpatj]

Describe the bug

Upgraded from svelte-4 to svelte-5 and found that the muted attribute does not render in the video tag which prevents autoplay on Safari when using client side routing. This is also currently happening in my chrome browser as well.

This is a problem as it makes autoplay not possible by default. Browsers won't start a video automatically if the video isn't muted.

Looks like this was an issue prior for svelte-3 and svelte-4
#6536

Reproduction

try to add a video tag with the attribute muted, when you go into the dev tools it doesn't render it in the actual html. It does appear in the properties, but I'm still getting issues with autoplay. I assume this is related to the muted attribute not actually being rendered?

It appears that even the muted property is always true even when explicitly passing false too. not sure if this is intended behavior but furthers my suspicion around the muted attribute

Looks like it might have been actually browser settings were blocking autoplay for some reason. Sorry all. Hopefully this helps someone
