Many times on four different hardware devices.

Steps to reproduce

  2. Scroll down the "Interactive map" and tap it. The screen flickers white then returns to its previous state. (The "Interactive map" is implemented with the Maplink template:
  3. Tap the map again. The screen goes almost completely white.
  4. Can no longer interact with the Wikipedia app, and it has to be force killed.

Expected results

Interactive map displays as it does in desktop browser.

Actual results

No interactivity, app freezes and has to be killed.
