`<dialog>`, in browsers that support it, has user agent styles of `dialog { display:block; ...} dialog:not([open]) { display:none; }`
by forcing it to `display:block` in the shim, the dialog is shown even when closed. There's no clean way to shim this for non-supporting browsers,
but arguably these browsers would have further problems with pure `<dialog>` usage anyway, and it's up to authors to then use different elements/shims.

1. It's == "it is"

2. The subject of the sentence is "Only one" (not "these") so the verb must agree with it.

Feel free to do nothing with this change, use it, etc - I just saw this while reading through the code.

Uses orphans/widows trick from @fran-worley at https://github.com/twbs/bootstrap/issues/20925#issuecomment-333492739.

Fixes #20925.

Removes the .justify-content-between from a navbar form example given it's the default style. Instead, mention how to adjust this and link to flex utils.
