- Extract all fonts and all font weights from the theme
- Load all required weights per font
Not clear 100% what is the root cause. But the (missing font weights?) loaded fonts did cause some incorrect initial tooltip width measurement that lead to an out-of-viewport tooltip placement. Depending on the tooltip text and the monitor (size + scaling) the measurement might result in a fractal width. In case the tooltip was placed right on the horizontal end of the viewport this then lead to a horizontal scrollbar which potentially caused an additional vertical scrollbar resulting in a layout shift.
Once the tooltip was rendered, the placement got corrected. Depending on the mouse placement, however, this issue caused an infinite loop of appearing and disappearing scrollbars.
Fixes#1016
