Vertical scrollbar is being hidden, when Twitter Bootstrap 3 modal appears, and returns, when modal is hidden. Since certain elements on my page varies its position on whether vertical scrollbar is or isn’t visible — this produces an overall not to good looking effect:
Is there any way to prevent this and force vertical scrollbar to stay on screen all the time, even during displaying of Twitter Bootstrap 3 modal?
I’m using modals generated by Yii2 framework, but I doubt, that this is framework issue. Seems to be more like core Twitter Bootstrap 3 problem.
