SyntaxError: Void elements do not have end tags

Prettier 1.15.3 Playground link

--parser vue

Input:

<template>
	<Input type="text" placeholder="用户名" size="large" v-model="formData.usernameModel">
		<Icon type="person" slot="prepend" :size="16"></Icon>
	</Input>
</template>

Output:

SyntaxError: Void elements do not have end tags "Input" (4:2)
  2 | 	<Input type="text" placeholder="用户名" size="large" v-model="formData.usernameModel">
  3 | 		<Icon type="person" slot="prepend" :size="16"></Icon>
> 4 | 	</Input>
    | 	^
  5 | </template>

Expected behavior:

<template>
	<Input type="text" placeholder="用户名" size="large" v-model="formData.usernameModel">
		<Icon type="person" slot="prepend" :size="16"></Icon>
	</Input>
</template>

I try the same code in prettier@1.11.1, it works.

@playwolsey The fix will be available in the next release (1.16), or you can install the dev version from GitHub (npm install prettier/prettier) as a temporary workaround.

@balupton This issue is for --parser vue but it seems you’re using --parser html (index.html), which is considered HTML5 and tag names are case-insensitive there. Could you open a new issue with more details (e.g., playground link, why are tag names case-sensitive there)?
