CSS selectors get overridden by narrower selector at style.css when using Seven

Note that the three solutions suggested above go from more specific to more generic and all of them currently work properly with Seven and Garland
Nevertheless, I suggest not to consider the first one, since it is too specific and a more generic case might fit in, like considering others filters getting in #582622: provide hook for dblog_filters
(which that patch's testing was how this issue arose)

@#3
the first option is just to fix a bug "ala D6", resulting in consistent behavior between current D7 administrative themes: Garland (which currently works for D7) and Seven (which currently doesn't get these styles and <select> lists tight together without any margin/padding)

the second option would be "a more major change" which shouldn't get started to be explored/tested/debated "so close to D7 alpha"

also note, that currently (today's D7) dblog.css has the following firsts rules:

.form-item-type, .form-item-severity {
  float: left; /* LTR */
  padding-right: .8em; /* LTR */
  margin: 0.1em;
  width: 15em;
}
#dblog-filter-form .form-type-select select {
  width: 100%;
}
#dblog-filter-form .form-actions {
  float: left;
  padding: 3ex 0 0 1em;
}

the 2nd and 3rd rules are targeting #dblog-filter-form .form-???
what I suggest to fix the bug that arises with Seven is to use the same "id selector" for the 1st rule

tested OK with D7 tarball (2010-Jan-05)

patching file `modules/dblog/dblog-rtl.css'
Hunk #1 succeeded at 1 with fuzz 2.

I would recommend considering CSS patch attached to #582622-49: provide hook for dblog_filters
(it is over there for testing that other issue, but seems more flexible/accurate)

uhh, 10 years for such a tiny patch...

be aware of re-roll typo: missing space
