Invalid code when namespace is followed by HTML comment

[joemaller]

@prettier/plugin-php v0.10.2
Playground link

Input:

<?php namespace foo; ?>

<!-- HTML comment -->

Output:

<?php namespace foo;



<!-- HTML comment -->

Expected behavior:

<?php  namespace foo; ?>

<!-- HTML comment -->

Current output is invalid.

Notes:
This seems to be specific to namespace declarations. I wasn't able to reproduce the problem with other declarations, assignments or function calls.

Bug, feel free to send a PR

Found a few related examples. I suspect something about the way namespace is handled.

This is the same as the original issue, the HTML comment is irrelevant, any HTML text will generate the same result. The PHP closing tag ?> collapses up then gets lost:

Input:

<?php
namespace foo;

?>

text

Output:

<?php
namespace foo;



text

This next one might be two issues overlapping. namespace is left open as above, then the comment is wrapped as PHP. Might be related to this other one. #1228

Input:

<?php
namespace foo;

// comment
