formatOnPaste is broken when pasting inside a DOCTYPE section

[fbricon]

With "editor.formatOnPaste": true, when pasting <!ENTITY foo "bar"> inside the DOCTYPE section of:

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE article [

]>
<article></article>

the block is formatted as

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE article [
<null>
]>
<article></article>

instead of

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE article [
  <!ENTITY foo "bar">
]>
<article></article>

[fbricon]

This is equivalent to calling the "format selection" command on <!ENTITY foo "bar">

Here's the issue on the lemminx side: eclipse-lemminx/lemminx#682

Can I close this issue @fbricon?
