I've stumbled on this very obvious idea while working on a website with a lot of interactive items that lead to separate pages. Initially I thought it might be useful for users to have the last clicked or focused element on the page regain focus when user navigates back in history, so he/she could continue to tab their way through down the page - especially if the list of such elements is long enough.
I've also discovered this 17(!)-years old ticket for Firefox, still unresolved. However there are no other expert opinions/strong arguments there that this feature might be desirable or undesirable. It is also claimed there that IE5 supported this, but I cannot say the same for IE11 — maybe they have this removed?
So should we consider restoring focus to the last clicked or focused element on a webpage a bad or good practice?
