I've successfully unignored the tests by removing the [Ignore] attributes that were temporarily added in PRs #5104 and #5107. The changes are minimal and surgical - only the test ignore attributes have been removed while keeping the legitimate ObjectDisposedException fix from PR #5105. Commit 365efe4
