Masonry issue on first load (Internet Explorer only)

Hi, first of all thanks for this lovely theme.

The bug I’m experiencing with Masonry takes place:
– only with Internet Explorer;
– on page first loads only.

For some reason, all the .post-container DIVs are all adjacents.
Comparing the source code, I’ve been able to see that the most notable difference seems to be coordinates of the absolute positioning, in particular the left property.

Please notice that a refresh of the page always solve the problem.

One more thing: I’m using Baskerville with a child theme, mostly to make changes to the color scheme.

I look forward to solve this. Thanks in advance!
