MSEDGE "View the details of digital signatures in PDFs" not working
Today lets review the MSEDGE build 107.0.1418.56 (Official build) (64-bit), with my test Certificate based signed PDFs, after several updates and restarts they continue to show the top strip stating that the PDF is digitally signed (and a new menu item appeared with the name "Digital Signature"). NOTE: There was a build (between my last post and this one) where this behavior disappeared, but then after a phew build updates it started to show again.
My tests feedbacks:
* [improved] The e-invoice certificate-based digital signed PDF (EU qualified certificate) states that all signatures are valid, and finally it has the same behavior as my test e-invoice below. when I click "View Signatures" it says that the Signature is "Unknown", but when I click the "View Certificate" -> NOTHING HAPPENS 😞
* [staled] PDF (created from a test word doc) signed with my government citizen card (smarcard eIdentity with issued certs for document digital signing), the digital signature top strip states that some signatures could not be validated (even thou they can be validated by the Adobe Reader, and the Root /Issuer CAs are in the OS Certificate Trusts) and when I click "view signatures" it says that the Signature is "Unknown", in terms of certificate it says "Not available for this signature" (even thou there is a certificate attached to the signature that I can view and do my own validation in Adobe Reader).
* [staled] in a test e-invoice digitally signed with an advanced certificate that has known validation issues (checked with Adobe Reader), when I click "View Signatures" it says that the Signature is "Invalid" that is correct, but when I click the "View Certificate" -> NOTHING HAPPENS 😞

lets review the MSEDGE build 112.0.1722.58 (Official build) (64-bit), with my test Certificate based signed PDFs.
- Current (Skia) PDF Engine: Exactly the same behavior as mentioned before
- New (Adobe) PDF Engine: Exactly the same behavior as mentioned before BUT now when I click the "View Certificate" (where it appears, because there are some PDFs that are certificate signed but this function does not appear) -> a popup window appears with the certificate info (but nothing about why the signature is invalid or unknown, it should use the hierarchy windows trust right?)
Note, I should remember that in the Adobe Acrobat Reader desktop app this certificate signature issue does not happens (I was hopping that changing to the New (Adobe) PDF Engine this issue would go away, but unfortunately it did not)
