Media toolbar spacing inconsistent across views

[desrosj]

The media toolbar is present on both list and grid views. The padding on the dropdowns and buttons, though, is inconsistent.

Tested patch on Lenovo ThinkPad Windows 10, in Firefox 59.0.2 and Chrome 66.0.3359.139. Changes looked good in both browsers. Also uploaded svn version of patch.

I applied the patch and it looks much better.

However, in order to keep the spacing consistent with media grid view the margin I believe needs to be 6px instead of 8px.

.post-type-attachment .wp-filter select {
    margin-right: 6px;
}
