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

• Go to an article with no ToC (for example this one). Make sure the menu is also hidden.
• Try to triple click on the page title to select it.

What happens?:

• When a page does not have a ToC or the main menu on the left, you have the arrow when hovering the title with the mouse, so you have to left-click, hold and move the cursor to mark the title. Once you do this, the I-beam pointer appears (and then you can also select the title by triple clicking on it).
• When there is something on the left, like the ToC or the expanded main menu you have the I-beam pointer, so you can just triple-click to mark the whole title.

What should have happened instead?:
It should be possible to select the page title by triple clicking on it, no matter whether the menu or the ToC are visible.
