Hover Broken from WordPress 6.0

The error must be caused by a plugin you are using (caching plugin?) or something else. Are you using the standard editor? && is used quite often in the Javascript code and not only for hover.
Working example.
(On the english site the Plugins GitHub version is running, it is unstable. But the WordPress version of the plugin ist running on the german site. On both sites is no problem with this.)

Agree with the && being common.

This is running in a clean install of WordPress 6.0.2 on Local and with no other plugins. Only the instance in that if statement with nested conditions is impacted. All the other && instances render properly. I even commented out the Jshrink and the problem persists.

I will try and write my first ever minimal shortcode and see if I can reproduce it. I don’t think it is your problem.

I will leave it open for now as you may need to re-factor as a work around

I have managed to do a minimal test that reproduces the problem. It only is a problem for an if statement nested in a for loop it seems.

I made a minimal shortcode and noted in the comments.

add_shortcode( 'test_ampersand', 'test_ampersand' );
function ta_init(){
 function test_ampersand() {
	$text = '<script>';
	ob_start();
  ?>/*<script>*/
  if (1==1) {
	if ((1 != 2 && 2==2 ) || 3==3) { null}
  } // Works
  for (var i=0; i < 2; i++) {
	  if (1==1) {
		if ((1 != 2 && 2==2 ) || 3==3) { null}
	  }
  } // Does not work
  if (1==1) {
	if ((1 != 2 && 2==2 ) || 3==3) { null}
  } // does not work now...
  <?php
  $javascript = ob_get_clean();
	$text = $text . $javascript . '</script>';
	return "\n".$text."\n Some Text";
 }
}
add_action('init', 'ta_init');

I will raise a gutenberg bug now.

I have only been able to recreate this with Laragon under Windows. Both with php74 and with php81. On my hoster under Linux it works.

https://github.com/WordPress/gutenberg/issues/44476

Solution found here:

in php/hover.php:

$text = '<script><!--';
...
$text = $text . $javascript . '//-->'."\n".'</script>';

The problem only exists with Laragon and Windows.
What is your environment? Does this work for you?

I develop on a windows 10 box and deploy to hosted linux so this is very useful.

I vaguely recall the advice to enclose javascript in non properly formed block comments in PHP (or was it ASP) somewhere years ago (like almost last century). Thanks for taking the time on this.

But no, the problem still persists. I will keep an eye on the issue I raised in the wordpress world.

If this becomes a huge problem for me I will refactor that script out to a js file and submit a pull request to you. Other fish are on my plate at the moment.

Undo that last comment, It does work.
