Symfony version(s) affected

7.3.0-beta2 (& beta1)

Description

Hi, after trying to upgrade to Symfony 7.3.0 (first to beta1, then to beta2) I encountered the same issue on both versions.

The issue being:

Error: Maximum execution time of 30 seconds exceeded
vendor/symfony/asset-mapper/Compiler/Parser/JavascriptSequenceParser.php:93
preg_match($this->pattern, $this->content, $matches, \PREG_OFFSET_CAPTURE, $this->cursor);

Downgrading to Symfony 7.2.x fixes the issue.

I finally made some investigations today, and it seems a plugin for Prismjs (the "bash" plugin) causes the issue, but I don't exactly know why AssetMapper stops on it.
If I remove this specific dependency from the importmap it works without issues.

How to reproduce

git clone https://github.com/jmsche/asset-mapper-7.3-prismjs.git
cd asset-mapper-7.3-prismjs
composer install
symfony serve -d
symfony open:local

You can check the symfony-7.2 branch, where the only change is a Symfony downgrade.

Note that switching back to the main branch & running composer install works, but if you drop the cache (rm -rf var/cache/*) it will start to fail again.
