Bug Summary and Steps to Reproduce

Using the setting.

with 80 I get
This has been setup with the CPP inlay hints configuration to ensure it targets C++. I think for some reason the bug fix in https://github.com/microsoft/vscode/issues/205708 is not working for C++

Additional context
This issue was ported from the core vs-code team because they claim it is the cpp plugin issue rather than core.

Research direction
No source file or test is identified in the report. Reproduce the C++ inlay-hints behavior with editor.inlayHints.maximumLength set to 0, 1, 10, 20, 40, and 80, then trace the C++ extension's inlay-hint handling; done means each configured value limits truncation as expected.
