checkbox: check marks missing in second column when using column-count: 2

[osuritz]

md-checkbox broken when used with a container that use (-webkit-)column-count.

Artifacts in Chrome:

• All checkboxes after the one being clicked flicker
• Background correctly changes on the checkbox but the check mark is actually missing

Is there any updates on this? The bug still exists.

Updated the CodePen to Angular 1.6.7 and removed the browser specific styles. Thus it only uses column-count: 2; and I can still see the checkboxes in the second column are lacking their checkmarks.
