Description

jQuery.camelCase contains a CSS-only quirk that replaces-ms- toms-. This quirk is needed only in the CSS module and yet the data module uses it as well, makingelem.data('-moz-a', 'b') create anMozA key andelem.data('-ms-a', 'b') - anmsA key. Those use cases should be separated.

Due to needed breaking changes this is 4.0 material.

P.S. It would be best to resolve#3384 first.

EDIT: Description edited as part of this ticket has been separated to#3384.
