When creating or editing a new KB article, the "Article Body" will not increase larger than 435px. You can see from the screenshot, the "+" in the upper right is not available to increase the height of the window further.
Since we are not editing articles on a phone, I'd like my technical staff to be treated with respect and permit them to increase the height of the textarea until their heart is content.
How do I either (a) remove or, (b) increase the max-height limit for that specific textarea?

Yes, that's the exact article that does not say how to do the specific thing I wanted. Unfortunately, I have already rated that article as "Unhelpful".
Changing the `editor.height` value does not result in the "Article Body" field being permitted to be larger than it is by default.

In that case I have solution for you 😉
Create an onload Client script on kb_knowledge table.
function onLoad() {
tinymce.on('addeditor', function(event) {
var selectedElement = tinymce.get('kb_knowledge.text');
selectedElement.settings.height = 700;
selectedElement.settings.max_height = 1500;
selectedElement.settings.min_height = 1000;
}, true);
}
This should result in a larger editor:

Hi! I am coming to this very late in the party but I've been wanting to do this for aaaages. Ideally, I wanted to 'unlock' that field so I can expand as far as I want (like you can with these comments).
I tried to use your client script but it just makes the article body field disappear!
