Tasks under Headings with the name of the current file don't appear to be detected at all

[devzero]

Repro steps:

Create a new file with a filename "foobar"

in that file, create a task under a heading with the word foobar in it:
"""

the word foobar

• completed task

"""

The completed task above will not be matched on and the task will be ignored. If I change one byte in the filename of the header, the task will be archived properly
