Treemap zoom-out misrenders and does not fire perspective-click event

[texodus]

Bug Report

Steps to Reproduce:

1. Set a in Treemap config with at least 2 columns set as Group By columns
2. Click on a section of the treemap to zoom in
3. Click the group label to zoom back out.

Actual Result:

There appears to be some SVG update rendering glitch, only N = number of rectangles in the sub group are rendered in the 2nd rendering of the parent group.

Additionally, perspective-click is not fired on zoom-out. THis causes any linked or global-filter-position <perspective-viewer> elements to not update in these cases.
