add clear:both for the default gallery style

[mark-k]

some of the themes have a floating div which contains the date of the post. In those themes, when the gallery is inserted in the beginning of the post, the result is less then optimal.

Adding clear:both to the default gallery style should fix this.

Adding clear:both to the gallery by default will also break other themes which use floats for other items, Adding floats breaks my theme for example.

If a theme needs the gallery styles to be floated, Then theres no reason why the theme cannot be modified to output different gallery CSS.

Suggest closing as wontfix myself; leaving it up for someone else however.

(My 2nd paragraph was supposed to read "If a theme needs the gallery styles to be cleared, then....)

Agree. This would be a "filter" for a particular theme. This is also a dup of #7607
