Three weeks ago I redid my mobile viewports tests for the umpteenth time, and today I give you my overview. There is some progress to report, but also a lot of changes.

• getBoundingClientRect() is relative to the visual viewport in most browsers, but relative to the layout viewport in Chromium 50+ and Edge.
• Touch/Click.clientX/Y has the same problem: it is relative to the visual viewport in most browsers, but relative to the layout viewport in Chromium 45+ and Edge.
