fix(useStyleTag): fix hydration mismatch issue

[sibbng]

Description

The buttons in the useStyleTag demo are not working if this page is visited with full-reload. There is a hydration mismatch error on console. I thought changing the value of isLoaded immediately on client side is might be the cause of the issue. I wrapped it with nextTick. The hydration mismatch error is still there but at least the buttons are working now.

I think instead, we should execute the immediate load() in tryOnMounted
