Helix precommand is expanding semicolons in strings to new lines. This caused issue #2056. A temporary solution to that issue was made in PR #2069, but this needs to be investigated further and hopefully changed back.

According to https://github.com/dotnet/arcade/blob/main/src/Microsoft.DotNet.Helix/Sdk/Readme.md, it looks like semicolons are escaped with semicolons. So to get an actual semi-colon in the strings we need to use ;;. A PR for this in this and the runtime repo will be up soon.
