Steps to reproduce:

Go to this link, press crtl + f, search for "MySQLIntegrityConstraintViolationException" and hit enter twice. The second match will be in the right panel where the hot questions disappear (The whole right panel disappeared for me, including the "Related" panel)

I tried that on two machines, on both Chrome and Internet Explorer.

Can someone validate this please?

    Reproduced; the linked question on the right is wider than the space in the sidebar, and the highlight 'scrolls' the sidebar div to reveal the part of the link that matches the text. Apr 8, 2014 at 10:07

    In other words, the whole sidebar is 'hidden' because a previously hidden overflow on the right has been moved into view. You could re-reveal the hot questions list by searching for 'hot network questions', for example. Apr 8, 2014 at 10:07

    We need to hit enter thrice now, because the OP of that post edited it.

This is caused by the linked question in the sidebar. It's full title is:

com.mysql.jdbc.exceptions.jdbc4.MySQLIntegrityConstraintViolationException: Duplicate entry '' for key 'PRIMARY'

The long exception name doesn't fit in the sidebar, and is not wrapped. Only the first part (up to the j of jdbc4 is still fully visible. When your browser highlights matches, the sidebar div content is 'scrolled' to the left to reveal the hidden part of the link title that matches.

However, this means that the rest of the properly wrapped sidebar contents have now been scrolled out of view. They are all still there, but no longer visible:

sidebar is still there

The work-around is to search for 'hot network questions', and the browser 'scrolls' the div back into the correct position.

I'm not too much of a CSS wiz, I am not certain how to solve this for this specific page. There are not many linked questions with such huge un-wrappable titles, but perhaps it can be forced to wrap anyway. A word-wrap: break-word; on that element certainly works, but there might be undesirable side-effects that I am not aware of.

  • The workaround works perfectly.. Thanks :)

Added word-wrap: break-word; to the sidebar module CSS declaration, which fixes the issue with reallyreallyreallylongwordsbreakingstufflikethis.
