How to configure bug's description field not to be opened as pop-up window while editing description

[Rafi Barry]

Hello,
Does anyone know how to configure in Jira, for an already existing bugs, that when pressing the bug's 'Description' field 'Edit' button, that is inside the bug's page (the one that appears when hovering above the field, and not the button on the top left of the page (which is 'Edit this issue'), will give the option to change text on same page layer, and not to first open a pop-up / floating layer for editing all bug's fields?
I see this behavior I looking for, exists in other issue types in my Jira project, but I couldn't find how to set it as well for the bug issue type.
Thanks in advanced!
Rafi.
