[FIX] web_editor: minor tweaks IE11

In IE11 the values can be not string (for example a number and so not
have .indexOf method), but then there will no be !important bits and we
can just ignore this feature (which check if an overriding rule has an
!important flag).

There was another edge case when getting a "" set style, we get undefined.
