Issue hover not working for YAML and Markdown files #9125

The issue hover does not appear for issue markers in YAML and Markdown files. I encounter no problems with files in other languages, like SQL. I tested this with no other extensions enabled.

• Extension version: 0.174.0
• VSCode Version: Code 1.144.0 (2c33b50b16c472efe58357d1d2a8a5414bc23fbf, 2026-10-27T20:18:03Z)
• OS: Darwin arm64 27.2.0
• GitHub Product: GitHub.com

Steps to Reproduce:

1. Open a markdown or YAML file with issue markers
2. Hover with mouse over issue marker
3. No hover window appears
