When opening an archive with more than one file, it's not possible to extract them by a single drag and drop. User must either go through the button "extract" and then select the folder, or drag every single file into the destination folder.
It's not a problem is files are inside a folder, as it's enough to extract the containing folder, but it is, when files are separate.

Reproducible: Always

Steps to Reproduce:
1. Open an archive with multiple files not organized in folders
2. Select all of them
3. Drag the selection to a destination folder opened in dolphin or whatever file manager
Actual Results:  
Just the file you put the pointer over in order to drag the multiple selection will be extracted. Therefore you have to repeat the procedure for each file

Expected Results:  
All the selected files to be extracted in the destination folder
