Bug - Label: canceling an inline edit with Escape keeps the discarded draft text

[fallmo]

Describe the problem

Pressing Escape while editing a label reverts the displayed text to the original children, but does not reset the component's internal currValue state that backs the edit input. Reopening the editor shows the draft text that was supposedly discarded.

Expected behavior
Escape should discard the draft completely. Reopening the editor should show the original children text, matching what the label displays.
