Though this restriction has been lifted in HTML5, an ID should start with a letter for compatibility. https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/id Signed-off-by: Tomas Cohen Arazi <tomascohen@theke.io> -- You are receiving this mail because: You are watching all bug changes.
