Publish button on Ask a question page not working correctly

[Georgi]

Sup fellas!

Noticed fewer questions lately than usual? Or is it just my browser/OS combo (Chrome on Ubuntu) where your question form is bugging hard?

Reproduce:

1. Click the Trello button on the Ask a question page.

2. Fill in all fields with seemingly valid content.

3. Click the Publish button.

4. Screen only jumps, nothing else, no error messages.

5. Click Publish again.

6. This returns to the Ask a question page.

7. Click the Trello button again.

8. The form now shows error messages (below).

9. Click Publish again.

10. Finally reaches the published post.

Expected:
Either publish the post right away, or show errors immediately (duh).

Error messages:

1. Correct the highlighted errors and try again.

2. Your post has been changed because invalid HTML was found in the message body. The invalid HTML has been removed. Please review the message and submit again.

Worth noting: the first time the hamburger menu is clicked, it only changes to an X icon. Clicking the X changes back to hamburger, and only then does clicking hamburger show the expected menu.

Best,

G.
