[BUG] Non-persistent strikethrough

[KeyanAbtahi]

WHAT:
When an entry is marked as complete, the strikethrough works, but refreshing the page or loading the page at another time has reverted the change and removed the strikethrough, despite the "Mark as complete" button state being active. When clicking the entry to hit the button, it shows "Mark as incomplete." despite no strikethrough effect being there.

REPRODUCTION:

• Load the calendar.
• Mark an entry as complete.
• Reload the page.

OTHER INFO:
The domain is .instructure.com.
The latest version of the extension & Chrome is used.
WIN 11 OS.
