[BUGFIX] Wrong selector extraction from minified CSS

[OzzyCzech]

Emogrifier have problem with minified CSS code

First character from first selector is lost:

html,h1,.class{color:red;} => tml,h1,.class {color:red;}

Can you reduce the CSS test data to a minimum that still has the problem? Currently, I do not see what the exact problem is: two selectors, or no spaces, or two rules for the same property?

Maybe you can also change the test name to show what the exact case is.

In the commit message: css -> CSS

See var_dump of $matches on line 308

array(2) {
  [0] =>
  array(3) {
    [0] =>  string(17) "html{color:blue;}"
    [1] => string(4) "html"
    [2] => string(11) "color:blue;"
  }
  [1] =>
  array(3) {
    [0] => string(16) "html{color:red;}"
    [1] =>  string(3) "tml"
    [2] => string(10) "color:red;"
  }
}

Second selector it's just tml

I'd prefer to have the element name here in the assertContains.

[OzzyCzech]

done

[oliverklee]

I'd prefer to have two different properties here (or even better: two different element names) so that we don't test attribute overriding ("the last one wins") or "two attributes for one element" here.

[oliverklee]

And let's have two tests: One for the first selector and one for the second/last selector.

[OzzyCzech]

we need there have two elements in minified CSS - that's the point first one match well second not match at all

what about

p{color:blue;}html{color:red;}

Will be enough?

[oliverklee]

Yes, that would be perfect.

it's there
