Popup positioning improvements (#2135)
* Rename elementRect to sourceRect * Add getRects function to TextSourceElement and TextSourceRange * Add jsdocs * Remove unnecessary valid parameter * Remove default parameter * Make optionsContext optional * Remove unnecessary checks * Update sourceRect to use left/right rather than x/y * Update the return type of Popup*.getFrameRect * Rename some unrelated rect vars for disambiguation * Disambiguate between Popup.Rect and Popup.ValidRect * Move sourceRect destructuring * Pass multiple source rects * Simplify * Change Rect to use right/bottom rather than width/height * Update how popup offset is applied * Simplify frame offset * Remove _applyFrameOffset * Use right/bottom rather than width/height * Simplify some positioning settings * Update parameter names for clarity * Fix typos * Refactor data type for _getPosition* functions * Support using multiple source rects * Combine _getPosition functions * Refactor * Expose after dataset value * Consistently use this's property * Add jsdoc
