Description

Tiny changes that improve accessibility. Should hopefully not take longer than a minute to review.

What kind of change does this PR introduce?

  • Bugfix

Issue

What is the current behavior?

#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?

  • 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.

On Behalf of DB Systel

* geosolutions-it#10158: set HTML document language once per mount/update

As requested, the document language is now set when the component is mounted or the language is changed instead of with every rerender.
