Disable self-closing tag if empty

[lacherogwu]

Describe the bug

Hello,

I think when the html tag is empty, it should use self-closing on format.

When I'm writing code, sometimes I write just boilerplate of HTML tags before I implement any styles and it's kinda annoying that it's closing empty elements, and to be honest it doesn't really make sense...

If the tag is not empty and contains any attribute so I believe self-closing will be the right way to go for e.g.

<div class="a" /> ✅
<div /> ❌
<div></div> ✅

Thanks!

Reproduction

Write any HTML tag and save the file I use Prettier for formatting, and auto-format on save

I agree. In fact I'd prefer the option to completely self closing tags for plain HTML elements. It even self-closes auto-closing tags like <br> or <input>. I think it makes the code actually uglier.

I think html compliant should be preferred like prettier core and we can adopt the core option.

Have you fixed the issue somehow?

In prettier-plugin-svelte version 3 tags will be left as-is.
