#10158

Bad Lighthouse Accessibility Score

What is the new behavior?

Better Lighthouse Accessibility Score through:

• Setting Document language
• Fixing a heading that should be a div
• providing a logo with an alt tag
• linking scale label with its form element
• enabling browser zoom

Breaking change

Does this PR introduce a breaking change?

• [x] No

Other useful information

Too much Zoom does seem to break the layout, but handing that responsibility to the end user is more accessible for people who need larger controls than disabling it. Map zoom is unaffected, and since using browser zoom enlarges map controls, users who tried zooming into the map using browser zoom should be able to notice the actual controls and recover from their mistake.
