Boot partition space insufficient on Huawei Mate S

[patrickjauernig]

With the most recent version, Magisk fails for my Huawei Mate S running Android 6.0. Magisk used to work at least up to version 6 (9 and 10.2 both do not work).
I have uploaded the clean boot image and the modified one for you:

The modified one is from Magisk 9. Magisk 10.2 does not generate any log files at all for me (at least under /cache/).

Obviously, my boot partition is too small / the generated boot image too big:

Repacking boot image
! Boot partition space insufficient
! Remove ramdisk backups and try again
! Boot partition size still too small
! Unable to install Magisk-

The problem still persists - I cannot install Magisk on Huawei Mate S running Android 6.0. I have tested this with versions up to 13.1 (latest).
During the installation it does not show any visible error (opposed to my first post).

I have uploaded both images as well as a recovery.log:
