b4 confusing separate patches in one series as different versions of one patch

[wens]

With b4 v0.12.4, while applying the patch series from message ID 0240516122102.16379-1-yunfei.dong@mediatek.com,
b4 seems to be confusing the individual patches as different versions of one patch, and only applies the one patch it considers the latest one, while ignoring the other 23 patches:

Not sure if it's because of the comma in the subject prefix or something else.

Yes, it's because of the comma in the prefixes. Sorry, but I cannot fix this one -- please ask the author to submit a well-formed series.
