Compare local Wikidata contribution page for user "Masai giraffe" with global contributions of said user

What happens?:
The global contribution page shows a high added byte count for the edits of the user in question. For instance, the most recent Wikidata edit has added 56,194 bytes according to the global contributions page, whereas the actual count is 168 bytes. Similarly, the most recent edit to an item added 936 bytes, but the global contributions page reports 186,751(!) bytes.

What should have happened instead?:
The amount of bytes added or removed should be synced for Wikidata edits.

Software version (on Special:Version page; skip for WMF-hosted wikis like Wikipedia):

Other information (browser name/version, screenshots, etc.):
It appears that Wikidata is only affected (edits for Meta are unaffected by the bug).
