Comment:

 As the patch for #59602 addresses more editor issues now,
 [attachment:"58355.2.diff"] makes some similar changes for Twenty Sixteen
 plus a few more:

 - Removes the redundant font size rules for table elements (`th`, `td`,
 `caption`) as 59912.2.patch proposed. When a user does not select a
 special font size for a Table or Calendar block, the table cells continue
 to appear at 16px, inheriting from the `body`.
 - Corrects the `font-weight` for table `caption` elements.
 - Updates `[class^="wp-block-"] figcaption` to `figure[class*="wp-block-"]
 > figcaption` because the class lists do not begin with a `wp-block-`
 class anymore.
 - Changes `text-align` to `start` so it works the same way in RTL without
 needing to update the extra `.rtl` rule to a `[dir="rtl"]` selector to
 apply within the iframe. Anyone using the //editor// should have a browser
 that supports `start` (it's not worth changing on the front end). These
 changes apply to table elements plus figure captions.
 - Removes the RTL `text-align` rulesets because `start` makes them
 unnecessary.
 - Adds the RTL font selection in `editor-styles.css` for the iframe editor
 and Classic Editor. The non-framed editor would be more difficult to
 correct (because it adds `.editor-styles-wrapper` to the selector), but
 this font has not worked in any editor context for a long time (if ever).
