compileOnSave emits referenced compile output

[HolgerJeromin]

TypeScript Version: 3.7.2 (worked with 3.6.2)

Search Terms: project references

Code
ts_include_onsave.zip
is a solution archive for visual studio 2019.

Repro step
Compile the solution and look at the output file Controls\SiblingClass\Source.js.
compileOnSave on the file Controls\SiblingClass\Source.ts

Expected behavior:
"Solution build" and "compile on save" should generate the same js files.
Only logic from Hmi.Sibling should be emitted in both compile ways.

Actual behavior:
compileOnSave emits additional js code from Hmi.buttonClass which is referenced via project references.

I suspect #32028 is the source of the problem. (cc @sheetalkamat ) even if this was mentioned in the PR:

compile on save -> do not emit files that are sources of project reference redirects
