Rider still has troubles with unity when compilation happens

I often experience two problems:

1) less often, but often: if I leave the debugger attached and stop the execution, then I modify files, unity won't start the compilation until I detach

2) if I attach the debugger while unity is compiling, the debugger never attaches and unity never finishes to compile.

this is with unity 2019.1

Start by reproducing both reported cases with Unity 2019.1: edit files after stopping with the debugger attached, and attach the debugger while Unity is compiling. Done means compilation starts after execution stops and debugger attachment does not prevent compilation from finishing.
