'margin' is not honored when fixed width set up

[alvesev]

The issue is: 'margin' setting is not respected and panel at left edge will overlap panel at top edge in 7.0-4 (unexpected), however in 6.1-6 left panel will respect it's fixed 'margin' and will be placed lower at left edge - will not overlap panel at top (expected and configured in configuration file).

Issue exist in fbpanel 7.0-4 amd64 Ubuntu 18.04
Issue do not exist and all fine in 6.1-6 Ubuntu 16.04

In configurations top panel's height is 66, left panel's margin is 66. This should allow them do not overlap each other. Below are configurations for screen 1024x768.

Please find subj configurations in attachment (named as .txt in order to make them to be a files of a type known to GitHub issue posting interface).
