I was able to find and download Chromium 80.0.3987.0 (Developer Build) (64-bit).

Everything seems to work fine for me. No wobbling. Sigh.

Both work.

Are the "Show sidebar" button (lower left) or the "?" (help, upper right)
buttons visible?  If so, it uses JavaScript and isn't the "plain" version.

Do the keybindings work?  They work for me.

The sidebar isn't supposed to come back unless you click "Show sidebar".
I feel that with a narrow screen, if you've navigated to a page,
you presumably want to read it, and the sidebar would get in the way.

An idea, to make it more "discoverable":  When you navigate to a new page,
the sidebar stays up initially, but fades out after a second or two.
Maybe the same thing when you open the home page.  Does that sound
like an improvement?  I don't know how difficult it would to
implement, but probably not very: Perhaps just a simple animation that
gradually changes the alpha of teh background-color.

I can certainly move the automatic-show/hide-for-narrow-screens handling
out of info.css and into the DomTerm-specific kawa.css.
