[w3c/editing] execCommand commands listed in MDN but not in the spec (Issue #530)

zcorpan created an issue (w3c/editing#530)

https://developer.mozilla.org/en-US/docs/Web/API/Document/execCommand#parameters has the following commands listed that are not in the spec:

- contentReadOnly
- decreaseFontSize
- enableAbsolutePositionEditor
- enableInlineTableEditing
- enableObjectResizing
- heading
- highlightColor
- increaseFontSize
- insertBrOnReturn
- AutoUrlDetect

We should check which of these are supported in which browsers and decide for each to either remove from implementations or specify and implement in the others.
