Page borders change when I zoom in and out

When I create a page and zoom in on it, the page size extends either downwards or to the right. The images and tokens stay in their same place, but it gets extremely annoying as the page color behind a map that is supposed to perfectly fill the page will suddenly appear. Here is what i'm talking about: See? the dark grey page color appears because the page size is extending way beyond the page boundary. (And no, the problem has nothing to do with the Stylish css code I'm using, I've checked.) Please help!

Quoting Kristin C. of the Roll20 Dev Team: This is a longstanding issue since Roll20's inception. It is an issue with the HTML5's Canvas element. We've investigated this in the past, but it's stumped us every time we've looked at it. In order to fix this issue, it will likely require us to tear apart the entire element to investigate what is causing the expanding pages at certain zoom levels. Due to the man-power and time required to do this, we've never been able to dedicate enough resources to focus on this yet. This is why we're hiring to double up our development staff numbers to help spread the work load around.

I saw you give this same answer to somebody in a thread from over a year ago. Why isn't it fixed yet?
