Bug 105641 – [CSS Regions] Selecting text through nested regions causes weird and unclearable selection

• Status: RESOLVED
• Resolution: FIXED
• Component: CSS

[Zoltan Horvath]

If you have a region with a nested region inside what is rendered below the base region and you are trying select text
starting from the base region and ending it in the nested region, firstly you got a weird selection, secondly you can't
clear the selection. We could prevent this strange behavior by preventing the selection through different region flows.

It's just a missing result on that platform. I'm not going to add the result generated by my vmware-cr-linux, since it shows 1px difference compared to the results of the bots for some reason.
