Overview:
toggling a inline element's children between display:none/block appends an extra ::after pseudo-element.

Steps to Reproduce:
In HTML:
 - Create a <ul> element with some <li> elements as children
In CSS
 - Apply a CSS rule to the <ul> element setting the element to display: inline
 - Set an ::after pseudo-element with the content property to the <ul> element 
 - Set all <li> elements to display: none and then remove the display: none rule (with Javascript)

Actual Results:
Every time the display:none rule is removed from the <li> elements, the <ul> element gets multiple ::after elements

Expected Results:
The <ul> should only have 1 pseudo-element.
