"Copy permalink" button only works when padding area is clicked

[luminuu]

Describe the bug
On the permalink options above the title, the "copy permalink" on the very left side only works on mouse clicks when clicking into the padding area between the SVG icon and the border.
It does work with focusing the element via the keyboard and hitting enter.

To reproduce
Steps to reproduce the behavior:

1. Go to a saved post or page, where a permalink is available.
2. Click on the title, the permalink options appear.
3. Click on the "copy permalink" button on the left, exactly on the SVG image.
4. The permalink options close, but the permalink was not copied.
5. Open the permalink options again by clicking on the title.
6. Now repeat to click on the "copy permalink" button, this time in the white space between the SVG image and the border of the button. The permalink get's copied and the options bar doesn't close yet.

Expected behavior
Clicking on the icon itself should also copy the permalink and not close the options bar immediately.

This UI has been removed in favor of the sidebar panel. Thanks.
