This screenshot shows the custom indicator Win7 not respecting the screen margin

SUMMARY
Recently Latte-dock got the screen margins feature, allowing the dock to be suspended for the first time from the screen edge. This is great, but it's now time to fix some bugs. The first of them I noticed right away is that the custom indicators like Dash to Panel, Unity and Win7, all of them don't respect the new screen margin and still touch the screen edge, even if the dock itself is not touching it.

STEPS TO REPRODUCE
1. Increase screen margin
2. Use a custom indicator like Dash to Panel

OBSERVED RESULT
The indicator box is touching the screen edge while the dock itself is not

EXPECTED RESULT
Both the dock and indicator box not touching the screen edge
