inlay-hints possible race-condition: inconsistent insertion order

[Rudxain]

Summary

This only happens in Insert-Mode

Reproduction Steps

So I was typing this:

export const trim_low = (s: string) => s.trim().toLowerCase();

Which renders as:

export const trim_low : (s: string) => string = (s: string) : string  => s.trim().toLowerCase();

Note

Relevant deps:

• typescript-language-server@4.3.3 (global)
• typescript@5.6.3 (local)

I try to place the cursor just after trim_low to append "0" to its name, the cursor shows up after the hint rather than before. This seems to be intentional (see #5934), but the insertion order is inconsistent.

I don't know exactly how it happened (I typed fast), but I managed to append the "0" to the name, while forcing it to render after (right-side) the hint, rather than the expected "before" (left-side):

// the spacing shown here may not be accurate,
// as this is from my brain memory
export const trim_low : (s: string) => string 0 = (s: string) : string  => s.trim().toLowerCase();

I want to emphasize that despite the broken rendering, the LSP properly sees trim_low0
