Steps to Reproduce:

1. Open VSCode Insiders
2. Open any file with some code
3. Open Chat
4. Ask to explain the code

File context is disabled so it ask to provide a code (in stable build context is enabled by default so it just explain the code). Also it seems that it's not possible to add specific lines as a context.

Video below, left Insiders, right stable build.
