dl responsive table view

[regularfry]

Description

This patch is an implementation of the markup-swapping fix for #1092 . It introduces a few new elements: since the table uses a caption and we need to preserve that, but caption isn't valid outside a table, the dl implementation uses figure and figcaption to do the same job.

Tested so far on macOS Chrome and Safari, and the VoiceOver/Safari combination.

Also fixes #1123.
