Filter for \?\? in search results—result seems to depend on how fast I'm typing

[sliedes]

Describe the bug

It seems that the result of filtering for the presence of "??" in search results is possible when typing "??"—but only if done fast enough.

To Reproduce
Steps to reproduce the behavior:

1. Search for a text in "Search Listing" that gives some results where e.g. the Code Unit contains values like "?? 5Fh _"
2. Type a backslash
3. Wait for some time
4. Type a question mark

Repeat the same experiment without step 3.

Without a wait, I will be able to filter results where the text "??" is present. With a wait, I will not see these results.

Expected behavior

The result is the same with and without a wait.

Environment (please complete the following information):

• OS: Linux
• Java Version: 23
• Ghidra Version: 11.2.1
• Ghidra Origin: Distribution (NixOS)

We see the issue.

For now, if you turn off the filter globing (using the button to the right of the filter), then you should be able to filter as expected without using the backslash character.
