3rd-party filter rules should not override personal blocker rules

Describe the issue

I found that an EasyList classification of an image overrides a personal blocking rule for an image which I created using element picker.

One or more specific URLs where the issue occurs

https://en.wikipedia.org/wiki/Murder_of_Du%27a_Khalil_Aswad

Steps for anyone to reproduce the issue

1. Open the page above, open element picker.
2. Create a filter for one of the image elements on that page, mine is the following:
   ! 1.4.2016, 02:44:46 https://en.wikipedia.org/wiki/Murder_of_Du%27a_Khalil_Aswad
   ||upload.wikimedia.org/wikipedia/en/thumb/2/25/AswadStoning.jpg/220px-AswadStoning.jpg
3. Reload the page.

Result:
Image element is not blocked anymore due to easylist overriding the images on upload.wikimedia.org as whitelisted. However, I think that specific user-rules should override even easylist.

I just read https://github.com/gorhill/uBlock/wiki/Element-picker#the-removed-element-reappears-when-you-reload-the-page and I it is my opinion that personal filter rules should have precedence over 3rd party rules.

Use the important filter option -- that's its purpose.
