TYPO3 Core

After upgrading from TYPO3 9.5.27 to 9.5.28+, opening the reports module on our biggest site (260k+ files) leads to a timeout (set to 60 seconds in our current setup). Same thing happens in the install tool: Upgrades > Run upgrade wizards.
Our smaller sites are not affected by this.

I did some digging and I out found that disabling the new SVG sanitizer (Introduced in 9.5.28, see https://github.com/typo3/typo3/commit/0443b66463) upgrade wizard "solves" the problem, and the reports module as well as the upgrade wizard view in the install tool are working again.

Commenting out that new line in /typo3/sysext/install/ext_localconf.php works for me for now, as we don't have SVG/HTML files inside /fileadmin/, and SVG/HTML uploads are denied through [BE][fileDenyPattern].

Of course we could just raise the PHP max_execution_time, but it'd be nice if someone could look into this...
