Passing a string with a % to SetTooltip() causes garbage data to be printed

ImFormatStringV

If vsnprintf interprets the string passed to SetTooltip as a format string, it looks at va_list args which will always be empty. The result is the next pointer being formatted into the string.

ImGui.NET should allow for passing additional args to SetTooltip to allow the arg to actually be used as a format string.

I did just realize that a workaround is to escape the % with an additional % like this:
var str = $"{value:p1}% - {label}";

yeah, that's how it is, if you wanna read more about it there was a recent discussion about it over here.

Ah I see.

Not a big deal since it can easily be worked around, but it would be nice if this issue had higher visibility so future people like me don't spend a couple hours in confusion :)

Maybe I could do a PR to start adding a "known gotchas" section to the docs to highlight oddities like this.
