How do you know it is deselected and not just colored differently?

Here is a screen cast of the issue, reproduced on Firefox latest nightly (Build ID:20130423030935).

The issue is not reproducible on Chrome.

The text is not deselected. Its just that when we select a highlight/background color, the selected text is displayed in blue color.

Just try this-
1- Write some text, select it and choose a background color.
2-Now without clicking anywhere, click on the bakcground color again, it will show a tick on the color you selected previously for this text, which means the text is still selected.

Or if you now select the newly highlighted text, you will see that its blue in color. So basically, the selected text view has changed when we give background color to it.

When I try to change the background/highlight color of the text, the text remains selected, but is not visually shown that is selected, as in Chrome, for example.
This issue is clearly seen in the screencast. 
Here is a screencast example of how it should work(Chrome): http://www.screencast.com/users/mitzabmm/folders/Jing/media/39f2f52f-4061-42d1-a031-832fa5f005a7

Ok now its right. The text do remain selected but its not highlighted. Definitely it should be implemented. I too had a problem figuring out that what happened to the selected text. 

Actually it works like this- If we select a background for some text, then the selected text is shown without background and if we don't have a background for the text then selected text is shown with a background. I wonder why this scheme is used.

An uneducated guess: bug 234102 might be related.

Bulk-downgrade of unassigned, >=5 years untouched DOM/Storage bugs' priority.

If you have reason to believe this is wrong (especially for the severity), please write a comment and ni :jstutte.
