Title: Additional tests for Element#makeClipping(), Element#undoClipping()

See ticket #1063:
1. Current implementation doesn't work properly for inline `style="overflow:auto;"`
2. Inline style isn't restored properly after undoClipping() - it is replaced with computed style
3. Computing style with `Element.getStyle()` isn't needed - performance optimization is possible
