Fix map button out of position

[DanWebb]

The map button was attaching itself to the browser viewport instead of the locator widget.

This adds a dummy transform to create a new containing block so that the fixed element is forced inside.

Regarding the actual issue, I'm not exactly sure why this seemingly randomly started happening, my guess is a browser update related to shadow DOM?
