Variants

PointerDown(f64)

A pointerdown on the tab host. Selects the panel; and when it’s the second within [DBLCLICK_MS], enters title-edit mode. Carries the event timeStamp (ms). We synthesize the double-click from pointerdown because <regular-layout-frame> calls setPointerCapture + preventDefault on the tab’s pointerdown (to arm a drag), which suppresses the browser’s synthesized click/dblclick — so a native dblclick listener never fires on the tab.

Close

OpenSettings

The tab’s open-settings button (shown while the settings sidebar is closed, in the close button’s place).

ContextMenu(f64, f64)

EditInput(String)

Track the live <input> value while editing (drives the auto-sizer).

CommitEdit

Commit the edited title to the panel’s session (blur / Enter).

CancelEdit

Abandon the edit, restoring the previous title (Escape).
