Perl Syntax Highligting: Multi-line Logical Defined-Or operator corrupts highlighting for rest of file

[perilstar]

Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: 1.67.2
• OS Version: Windows 11

Steps to Reproduce:

1. Create a file with the extension .pl
2. Paste in the following code:

#!/usr/bin/perl

use feature 'say';

my $abc;
$abc //= 1;
# This bit looks right
say "\%abc: $abc";

my $xyz;
$xyz
  //= 1;
# This is coloured incorrectly
say "\%xyz: $xyz";

Wow, it seems to be an issue in GitHub markdown highlighting too.
