Modal backdrop not visible if modal is opened after scrolling #798

Closed ghost closed 2 years ago

ghost commented 2 years ago

Describe the bug (actual behavior)

When clicking on Modal, the backdrop will not be displayed on the whole page if modal is not shown in the initial page view.

Expected behavior

When clicking on Modal the backdrop would cover the whole page, no matter the Modal position on the page.

Reproduction

https://codesandbox.io/s/itwinui-react-modal-bug-pyy2pz

Steps to reproduce
  1. Open sandbox,
  2. Click on the second button. (same problem with one button as well)
  3. Most of the page is not covered by a backdrop

Additional information

Using the newest iTwinUI version. Edge, Chrome, Firefox browsers.

Possible solution: Settings these changes in scss fixes the problem (I think): .iui-backdrop { position: fixed; height: 100%; }
