A couple of glitches occur with the attribution function in Build:

1 — When highlighting text attached to an attribution, the pop up is blank and the link can't be retrieved.

See the first attribution in the introduction to this Byte, with accompanying screencap:

2 — When trying to delete an attribution, the question mark simply shifts to another part of the text it's associated with.

See the screencap below from this Byte: https://build.rumie.org/byte/rbHGSlSXcWltsJCaAkMn

It was originally attached to "avocado toast" (switched it to a link for publishing purposes). Question mark was after "toast" before deleting but shifted to after "avocado" after deleting.
