User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.2; en-US; rv:1.8.1a3) Gecko/20060707 BonEcho/2.0a3 Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1a3) Gecko/20060707 BonEcho/2.0a3 The History menu shrinks and loses the 10 item recent history list, after the user touches and expands the Recently Closed Tabs option. If the user quickly moves over the Recently Closed Tabs option (without it expanding), then no shrinking occurs. (The shrinking is caused by the loss of the 10 item recent history list. Navigating to another menu and then back to the History menu causes the 10 item list to be repopulated.) The menu shouldn't shrink and disappear out from under the mouse cursor. Reproducible: Always Steps to Reproduce: 1. Click on the History menu 2. Click on the Recently Closed Tabs entry to expand it 3. Put the cursor on another History menu entry (like 'Show in Sidebar') and see it shrink in < 1 second right before your eyes. Expected Results: menu shouldn't shrink and disappear out from under the mouse cursor
