[[Rolls]] fail when using nested macros

When creating a macro with, for example, [[1d20#DEX]], the roll fails, or rather is just not registered as a roll at all. The workaround I've found is to add a space between the macro and closing braces ([[1d20#DEX ]]). Is this working as intended, or should macros not be reading ]] as part of another macro's title given its special nature? Reproducable on Firefox 23+ and Chrome 30+ in Windows 7 (the only places I tested it).

What is the body of #Dex? - Gauss

+3 is all that is in #Dex.

The end brackets won't work after a macro unless there is a space in between the macro and the end brackets. Normally, when you use autocomplete to complete the macro it puts a space in there for you. However, by putting 1d20 and #Dex next to each other (no space) the autocomplete isn't coming up. Solutions: 1) Put a space between 1d20 and #Dex, then use autocomplete. 2) Put a space after #Dex. - Gauss

That's been my go-to workaround, I was just wondering if ]] should be seen as a valid character combination for macro names since it's already established as part of a roll.
