+1 to the feature request.
I’d like to suggest to take it a step further and handle stripping out all markdown syntax from the outline.
e.g. I often end up with notes with outlines like
[[Installing Python on macOS]]
macOS 11 workaround
Details
[Rationale or other things not to do](https://opensource.com/article/19/5/python-3-default-mac)
`python -m pip` or Don't run `pip` as a tool
Any markdown syntax (wiki-link, web link, inline code, emphasis / italic) become distracting in the outline view
