Some valid module ZIP files are recognized as BIN by Magisk file selection instead of ZIP - unable to flash

Device: Redmi 7A - Matrix ROM # uname -a Linux localhost 4.19.325-MiThorium-g713d52bb78c9 #1 SMP PREEMPT Sat Jul 5 16:50:43 IDT 2025 aarch64 Toybox Android version: 15 Magisk version name: 30.7 (D) Magisk version code: 30700 Issue is VERY strange, happens on Android 15 (did not reproduce on A10). Only some ZIP files that are 100% perfect/valid and install OK in all cases (md5sum confirmed) are detected by Magisk on A15 as BIN and as such it is not possible to Flash them from file selector. Renaming the file a tiny bit, without making a copy (so, same permissions, same inode) and it is immediately available to flash as a ZIP.. The GUI/file selector shows as ZIP and not BIN anymore. I've spent few hours trying to figure out what is reason, but cannot find it!!

Unsure which log to upload since this is a file-detection issue, the program thinks it's a BIN file for some reason, and that happens on Android 15 only.. running same steps on A10 on similar device identical md5sum zips are loading file.
