Menu doesn't expand while backtracking

[llllvvuu]

To reproduce, create two files, abcd.md and abef.md.

https://github.com/artempyanykh/marksman/assets/5601392/63950fa6-e703-4cce-ba66-9dba18195463

abef.md does not appear until I type forward after deleting the text.

Expected:

• Once backtracked to /ab, abef.md should appear.
• Once backtracked to /a or /, abcd.md should not disappear

This is using Neovim with nvim-cmp. Backtracking works as expected with other LSPs.
