Deleting a line containing a mark should delete the mark too.

When using deteting command like dd or d {line movement}, it should also delete the mark in that line according to Vim's manual.

The following content may have nothing to do with the bug.
I feel weird about the behavior of deleting line of Vim. I have tested the mark deleting behavior several times, I find that if you use d w command until deleting the whole line, the mark will not be deleted since the command is not a "line" command. It is difficult for me to distinguish what is "line" change. I appreciate it if you could tell me something about it.

Reproduce the behavior with dd, d followed by a line movement, and repeated dw commands while a mark exists on the affected line. Read Vim's mark-deletion behavior in its manual and compare it with the extension's current behavior; done means linewise deletion removes the mark as specified without changing the documented behavior of non-linewise deletion.
