Problem with including markdown as language for Emmet

Version: 1.48.0-insider (user setup) OS: Windows_NT x64 10.0.18362 Steps to Reproduce: 1. Open settings.json 2. Add the setting: ```json "emmet.includeLanguages": { "markdown": "html" }, ``` 3. Open a markdown file and try to use emmet, it does not work. There is a workaround discussed in [this stack overflow question](https://stackoverflow.com/questions/49956963/markdown-not-using-emmet). The following will work: ```json "emmet.excludeLanguages": [], "emmet.includeLanguages": { "markdown": "html" }, ```
