MatchOptions.IgnoreCase has a huge impact on Regular Expression Match functions

Microsoft Power Fx Console Formula REPL, Version 1.99.0.0
Enter Excel formulas.  Use "Help()" for details, "Option()" for options.

>> IsMatch( "3", Match.Digit, MatchOptions.IgnoreCase )
false

>> Match( "3", Match.Digit, MatchOptions.IgnoreCase )
false

>> MatchAll( "3", Match.Digit, MatchOptions.IgnoreCase )
false

>> MatchAll( "3", Match.Digit )

  FullMatch   StartMatch   SubMatches
 =========== ============ ============
  3           1            <table>

>> Match( "3", Match.Digit )
{FullMatch:"3", StartMatch:1, SubMatches:
<empty table>}

>> IsMatch( "3", Match.Digit )
true

It shouldn't do that (always return false)... And that's not what it does in Canvas.

Reproduce the three expressions in the Microsoft Power Fx Console Formula REPL, comparing MatchOptions.IgnoreCase with the same calls without it. Check the implementation and tests for IsMatch, Match, and MatchAll, then verify that applying IgnoreCase does not make the digit pattern return false and that the behavior matches Canvas.
