Calculating collapsed borders for big tables is expensive, so we cache them and recalculate when needed.
|
|
Here we:
|
|
1. Remove DIV text, this requests layout for DIV, but only simplified layout for TABLE;
|
|
2. Change cell border color, expect that cache is invalidated and paint produces expected image.
