Summary Dynamically applied :empty pseudo class with display:none does not get unapplied
Ryosuke Niwa
Reported 2017-03-20 21:04:48 PDT
When tbody:empty contains display:none, and this rule is applied as a result of dynamic DOM mutation, the rule hides tbody successfully but inserting new content does not unapply the rule, resulting in the tbody to be forever hidden until the style recalc is forced on the element.
