The code here leads me to believe that the intention is for the sidebar
to be default visible on large screens (where `clientWidth` > 1080) and
hidden otherwise.
However, as previously written, if the `localStorage.getItem` call fails
(for example, if the user agent is not accepting cookies), then we fall
back to `sidebar = sidebar || 'visible';` — but `sidebar` is already set
to `hidden`, so the `|| 'visible'` never happens.
This results in the sidebar hiding itself on every navigation through an
mdBook, meaning if you're just switching between sections trying to find
something that you keep needing to re-open the sidebar.
Quoting from the HTML specification[1]:
A document must not contain both a meta element with an http-equiv attribute
in the Encoding declaration state and a meta element with the charset
attribute present.
So we remove the <meta> with the http-equiv attribute from our template.

* Fix: Scroll sidebar to current active section (#1067)
* Clean: Some code related to PR #1052
* Change `scrollIntoViewIfNeeded` with `scrollIntoView`
* Don't use onload event for sidebar scroll to reduce flickering.

* ui: improve menu folding
Fold/unfold the menu bar just by the amount of scroll, not by its
full width
* refactor: use a variable for the menu bar height
* Fix menu scroll jittering, remove hover folding smoothness
Rewrite it to use `position:` `sticky` and `relative` instead
of continuous programmatic position changes
On-hover folding-unfolding transition removal is a side-effect
* Option to display copy buttons.
- Added field to playpen data structure
- Communicate through window.playpen_copyable
- Javascript updated to check before displaying copy buttons.
* html -> html_config
Also:
- update description of copyable in source code.
- update description of line_numbers (my last PR to this repository)
- Added line numbers to config struct
- Added playpen_line_numbers field to hbs renderer.
- Added section to set `window.playpen_line_numbers = true` in page template
- Use line number global variable to show line numbers when required.
* Update print styles for new sidebar behavior
* Hide copy icons in print output
* Wait for mathjax rendering to complete before printing
* Remove old wrapping css
Browsers this old are already hilariously broken, so we don't need these fallbacks.
* Change mathjax script type
Chrome won't execute this if it's not marked as js
* Ensure page has rendered before printing
In certain situations Chrome willl fire window.onLoad before it's
done rendering. Add a 100ms delay to work around this.
