Input autofocus gets lost

Here, in flex objects editor the first field has autofocus flag. When page loads the field gets focused for a short time, but then it loses it:


No file or test is named. Start by locating the flex objects editor and reproducing the page-load focus behavior, then trace what removes focus after the initial autofocus. Done means the first field retains focus when the editor loads, with a regression test if the existing test setup covers this behavior.
