Bug 1312244 - Autocomplete popup does not close when anchor clicked a second time. r?Enn The popuphiding / popuphidden events are fired synchronously when the popup manager decides we're doing a "rollup" (closing the popups due to "outside" events). In the case of this bug, the "outside" event is a click on the input element in content. Here's the kicker though: we handle that popuphidden event and queue a message to content _before_ the mouse event that caused the roll-up is dispatched to content. This means that browser-content.js hears that the popup closed due to popuphidden first, sets its internal state of popupClosed to true, and then the MouseDown on the input field is processed. The nsFormFillController then queries browser-content's AutoCompletePopup, sees its closed, and tells the parent to open it again. This patch adds the norolluponanchor attribute to the panel, which causes us to ignore the rollup event if it happens to be targeted within the anchor rect. This means that we need to trust content to tell us to close the autocomplete popup if the input is clicked when the popup is open (and this is what bug 1183037, which this bug depends on, does).
