## [STCOM-1387](https://folio-org.atlassian.net/browse/STCOM-1387) The focus-trapping logic of Modal (via `focus-trap`) causes the `click()` event not to trigger on the download link rendered by `ExportCSV` because the link is appended outside of the focus-trapped element (in the body.) Approach: Rendering the link within the `div#OverlayContainer` places it in within the `focus-trapping` boundary. Since this element is always present in the stripes UI, it's okay to render here. For tests where the `OverlayContainer` may not exist, the logic falls back to the body. Additionally, the `exportCSV` logic would simply click the link and then remove it. This may not cause the focus to move, but it's a safe accessibility measure to return focus to the element it was originally on prior to clicking the download trigger. A similar fix is required in `stripes-util` since we're not sure how many ui modules use THAT version of `ExportCSV`... That PR: folio-org/stripes-util#91
