Safari 14 app signature cannot be verified (again after an update)

Hi,

This issue is back with Safari version 14.0.3 (15610.4.3.1.6, 15610)

I have a Mac running on Catalina 10.15.7 with Safari 14.

After that I noticed that Little Snitch cannot verify app signature (Code signature: Resource or signature modified). And when I run codesign on terminal it reports as follows:

codesign --verify --verbose /Applications/Safari.app

/Applications/Safari.app: a sealed resource is missing or invalid

[+ a number of files added]

Is this normal and expected behavior? Is the app signature somehow purposefully broken with Safari 14?

Thank you for your advice.
