When using Orion 1.0.0 (139), I find that when I hover over vertical tab entries on my macOS primary display with another display above it (I have several monitors), the preview does not draw to the right of the tab entry, but rather instead renders on the display above this main monitor. This is a strange issue, but Orion is using the full screen real estate and somehow I suppose it thinks it must draw the preview on the first available space it finds above the app...

The preview / thumbnail result should appear to the right of the vertical tabs.
