Steps to reproduce the problem:
I'm not sure if it's a bug or feature, but it's quiet confusing.

1. Open multiple tabs, like: https://bugs.chromium.org/p/chromium/issues/list
2. In 1st tab search for 'hours' (don't close search component).
3. In 2nd tab search for 'ago' (don't close search component).
4. Now the 1st tab has 'ago' in search.
5. If you open 3rd one and search for something, all tabs has the same pattern.

What is the expected behavior?
I would expect separate instance for each search, so I can perform different searches on different tabs/windows.

What went wrong?
The new search overridden all previous searches and removes the previous highlights on all tabs where it was used.

Did this work before? N/A 

Chrome version: 51.0.2704.103  Channel: n/a
OS Version: OS X 10.11.2
Flash Version: Shockwave Flash 22.0 r0

This is especially problematic when you want to compare two tabs with different search pattern, so the 1st tab losing the search highlighting on the previously selected area.

And problem when searching on different non-related websites. For example I go to Jenkins and I want to highlight some text to which I want to come back later on, I go to BBC and search for 'Sport', and then I'm coming back to my log and I can't see anymore my previous searches.

This also happens on different windows and across different people profiles. So one person could search for some pattern, then another person switch to their profile and their search will override their search patterns on all tabs which could be not relevant to their websites.
