Because DearImGuiInterpolatedStringHandler.NullTerminateAndGetString returns a span not including the null terminator, "" results in a 0-length ReadOnlySpan<byte>. This causes the byte* from the fixed statement to be null which is not correct in our case.
DearImGuiInterpolatedStringHandler.NullTerminateAndGetString should return a span which includes the null terminator.
