Steps to replicate the issue (include links if applicable):

• Have this edit panel active:

Whatever it is called now. Dunno if it is another useless revamp of the 2010 panel or some replacement.

• Open a page for edit, for example https://en.wikipedia.org/w/index.php?title=Special:Random&action=edit
• Click some button. In my use case I usually click the redirect button as I like to create redirects from alternative names for the article subject

What happens?:
Nothing.
Only after you add an extra step before clicking on the button namely:

• Click on the edit field to put your cursor there

does the button start to work

What should have happened instead?:

• The button shall insert its corresponding wikitext at the beginning of the page code, as the only text for a new page

Software version

Other information
As far as I remember it used to work well before the button style change for the panel.
