Syntax highlighting for variables incorrect where ? is treated as token separator

[SteveL-MSFT]

$foo?bar = 1

"$foo?bar"

only $foo is highlighted as a variable, this causes confusion to the customer as PowerShell treats $foo?bar as the variable (which is allowed)

PSReadline highlights correctly
