Steps to reproduce:

• Open template dialog at "narrow" screen size.
• Go to the sidebar pane (will be full-screen).
• Select a parameter which is not the first parameter in the list.
• Switch to the content pane.
• (Can also switch back to the sidebar pane for more bugginess.)

What happens:

• Nothing is focused in the content pane. The first page in the sidebar is selected.

What should have happened:

• Should have scrolled to and focused the content pane input corresponding to the selected sidebar **row.

Note:
For focus see T290975: Synchronize scroll and focus when template dialog is in narrow-screen mode
