Steps to reproduce

  <demo v-model:foo-bar="modelVal" @update:foo-bar="update" />

What is expected?

v-model:kebab-case and @update:kebab-case all work.

What is actually happening?

v-model:kebab-case not work，@update:kebab-case work. but if change to v-model:fooBar, they were all work. I see the compile result，v-model:kebab-case compile to onUpdate:foo-bar, @update:kebab-case compile to onUpdate:fooBar, this should be the reason ?
