Steps to reproduce the bug:
- Drag and drop several snippets onto a web page in edit mode to make
the vertical scrollbar appear.
- Drag and drop a popup onto the page.
- Drag and drop snippets into the popup so that the height of the popup
exceeds the height of the viewport.
- Try to scroll the popup downwards by clicking and dragging on the
scrollbar (not using the mouse wheel).
- Bug: the page is scrolled instead of the popup.
Note: This bug occurs in Chrome (not in Firefox).
This issue occurs because two scrollbars are present at the same
location (one for the page and one for the popup) and they overlap each
other. Normally, Bootstrap removes the scrollbar from the body when a
modal is opened, and this behavior was adapted for the #wrapwrap element
with this commit [1]. However, when transitioning to Bootstrap 5, the
code that overrides Bootstrap was removed instead of being adapted (this
was done in this commit [2]).
In later commits [3] and [4], we continued to remove code that updated
the scrollbar based on the opening of a modal because this code was
causing errors due to the fact that it was incomplete without the part
removed by commit [2].
This commit restores the original behavior (before the deletions made by
the aforementioned commits) by restoring the missing code and properly
adapting it to Bootstrap 5.
