>> I find it sad (to annoying) that these projects still use actual form elements instead of `contenteditable`, even though they're quite obviously full-JS (and probably not going to be submitted through HTML forms), given the difficulty of correctly styling, integrating and interacting with form elements.

I think this is because of performance. form elements are rendered differently and actions mostly result in a limited repaint and a couple events fired. contenteditable DOM elements are a lot more work to update.

I'm not sure about this hypothesis, when making a field editable requires inserting a bunch of dom nodes and trying to position your brand new input at the right place, it should be way more repaint that the NOOP of adding an attribute to the element.
