Prettier inserts whitespace between inline HTML tags

[harmenjanssen]

Describe the bug
Prettier will move all HTML tags to new lines, effectively inserting whitespace between them, which gets rendered by the browser.

To Reproduce
Create Example.svelte and include the following:

<p>Lucky number: <span>4</span><span>2</span></p>

Prettier will format this like:

<p>
  Lucky number:
  <span>4</span>
  <span>2</span>
</p>

Whereas it leaves an HTML file with the same contents alone.

Expected behavior

I would expect the inline elements to be left alone, and whitespace preserved.

System (please complete the following information):

• OS: MacOS Catalina
• IDE: VSCode 1.48.2
• Plugin/Package: Svelte for VS Code v101.11.1
