 **Bugfixes:**
 
 - Fixed an issue determining visibility when an element is hidden by an ancestor with a shared edge. Fixes [#27514](https://github.com/cypress-io/cypress/issues/27514).
+- Fixed an issue with 'other' targets (e.g. pdf documents embedded in an object tag) not fully loading. Fixes [#28228](https://github.com/cypress-io/cypress/issues/28228)
 - Fixed an issue where network requests made from tabs/windows other than the main Cypress tab would be delayed. Fixes [#28113](https://github.com/cypress-io/cypress/issues/28113).
 - Stopped processing CDP events at the end of a spec when Test Isolation is off and Test Replay is enabled. Addressed in [#28213](https://github.com/cypress-io/cypress/pull/28213).
