Welcome @anatolykopyl! 👋
Sorry you ran into a spot of trouble.

Could you share a sandbox with an example of the issue?
The one you shared:

1. has no link with query params in the example markdown
2. I suspect you are asking about backslash escapes on \& like so https://stackblitz.com/edit/github-5zebgm?file=src%2Fmain.ts

These are valid in commonmark, and does not cause an issue https://spec.commonmark.org/dingus/?text=%5Bexample%5D(https%3A%2F%2Fexample.com%3Fone%3D1%26two%3D2)%0A%0A%5Bexample%5D(https%3A%2F%2Fexample.com%3Fone%3D1%5C%26two%3D2)

If you're seeing an issue it is with another tool which cannot parse CommonMark.
