Sass Style Misspelling: $loadmask-backgorund
Loading mask's "$loadmask-background" variable is misspelled as "$loadmask-backgorund" in ExtJs 4.1.1. Which is not very intuitive if you're trying to override that variable in a custom theme.
Thanks for the report. Looks like this has already been fixed for 4.1.2
Bug report says fixed in 4.1., so this is probably a mistake, since it's not fixed in 4.1.1.
