In recent versions of Factorio, the editor window automatically adjusts its position to avoid overlapping with any mod_gui elements. This behavior eliminates the need for manual adjustments to address such conflicts.
From my testing, removing the following lines of code resolves the issue depicted in the first screenshot, allowing the interface to correctly appear as shown in the second screenshot.
