[Bug]: Snippet language mode search is inconsistent

[sansbyte]

Describe the bug

In the dialog for changing a Snippet's language mode, the search feature doesn't work in some cases.

To reproduce

1. Go to a Snippet
2. Click on the language in the bottom left of the snippet window
3. Type 'Bash', 'bas', 'bash', etc.
4. The 'Bash' language is never found. Instead, search narrows down to 'Handlebars'.
