 The second part of #17058, unable to view submenu on hover after toggling
 closed and collapsing the menu, is not fixed for Chrom(ium|e).

 This is because removeAttribute('style'), used internally by the jQuery
 removeAttr() function, does not work properly in said browser. Tested
 using Chromium 11.0.696.71 on Linux.

 Strangely if you try to observe the behaviour as it happens using the
 inbuilt developer tools it works as expected. You can only check that
 "display:none;" is still set '''after''' toggling the submenu closed.

 An alternative method I thought of to fix this was to use
 `.css('display','')`. This works in both Chromium and Firefox in testing.
 Any other methods?

 Note that the first part of #17058 isn't an issue since submenus are
 hidden by width = 0 when the menu is collapsed.
