Browser support review

[AlanSl]

All browsers have an error in console on window resize, chart.querySelector(...) is null - might be related to the resize chopping issue (most noticeable in Chrome for Windows)

Currently supported:

• Chrome (desktop)
  • [] [medium / serious] Some stacks get inconsistently chopped off right hand edge after window resize (especially on Windows)
• Firefox (desktop)
  • No specific issues

May become supported in future

• MS Edge (Windows 10)

  • [minor] Horizontal scrollbar appears after window resize, obscuring some buttons until user scrolls down

• Safari 11 (Mac)

  • No specific issues

• Safari (iOS)

  • Need to borrow a device

• Chrome (Android)

  • [serious] Weird / broken resize behaviour on screen rotation - goes tiny or off screen. Must refresh page after rotating screen
  • [serious] In portrait orientation, lower button panel is off bottom of screen. User can scroll down and see them but will have no reason to try to scroll down
  • [serious] In landscape orientation, lower button panel is off bottom of screen and user can't scroll down

• Firefox (Android)

  • [serious] Same issues as Chrome (Android)

• Opera shows same as Chrome
