Warning WInlineOptimizedField appear in some strange condition

I have a warning when working with VSCode, Projet [hashlink-debugger](https://github.com/vshaxe/hashlink-debugger) master, hld/Eval.hx, lastest haxe (it's a recent bug as I could not reproduce with 547b510).

The warning says "Inlining of cached field getName might lead to unexpected output (WInlineOptimizedField)", where `getName` is a function from `EnumValueTools`.

The warning does not appear when I just open the project, I always need to wait a while (such as after some minutes browsing the web).
The warning appear when I click+ctrl something (e.g. Value) and jump to another file, then return to it.
After a ctrl+shift+B (build), it will either disappear or give more warning on other files (seems depend on opened file).
After the warning appear, restart language server and rebuild will remove all warning.
