Data attribute names with single dash-surrounded letters cannot be accessed by the camel-case name

[Pointy]

Data attributes like "data-image-x-offset" should be accessible via ".data('imageXOffset')", but currently they cannot be. The ".camelCase()" function correctly translates the name, but the code that goes the other direction apparently mishandles this case.

Access by the dashed form of the name works of course.

More info: if the dashed form of the attribute name is used at least once for a given element, then the camel-case form subsequently works.

Confirmed, it's a bug in rmultiDash. Thanks ... I wish we would have been able to fix this in 1.6.3 but at this point it's a 1.7 item.

Possible solution is:

rmultiDash = /\B([A-Z])/g;
key.replace( newMultiDash, '-$1' ).toLowerCase()

Because it is a single character match, the index of the starting character of the next attempted match will always be one higher than the index of the previous starting character rather than being one higher than the index of the ending character matched in the previous match.

Or I should have said "...rather than being two higher than the index of the previous starting character if the previous attempt resulted in a match".
