1.7.1 ui-icon hover CSS bug?


[previously posted to jQueryUI group]
I have been fighting to get hover to work correctly for a ui-icon and
discovered the problem only appears when the ui-icon is enclosed in a
ui-widget-container.
So I created a test page (included below).
Then I started digging into the core css. I found the line that
causes the error. Line 22 of ui.theme.css from 1.7.1
The selector list for that line is ...
.ui-state-hover, .ui-widget-content .ui-state-hover,
.ui-state-focus, .ui-widget-content .ui-state-focus
This doesn't make sense to me. It appears the first two terms are
redundant. Match .ui-state-hover or match .ui-state-hover when
included in ui-widget-content.
Without knowing the intent of the design it is hard to say. My
thought was possibly to match combined classes. With CSS2 that is
possible, so I removed the spaces between the classes and the selector
list becomes ...
.ui-state-hover, .ui-widget-content.ui-state-hover,
.ui-state-focus, .ui-widget-content.ui-state-focus
With this modified CSS all three buttons in the following test page
have a functional hover.
Is this truly a bug in the theme CSS or am I missing something?
Thanks,
Troy
