Pseudoelement not rendered properly

[adityanichkawade]

There seems to be problem with the pseudo-element as it is not getting rendered properly with normalize.css applied.

I have attached the screenshot.

Without normalize.css

With normalize.css (not getting rendered properly)

Following is the code snippet:

.accordion-button:after {
    content: "\25BA";
    font-size: 1rem;
    float: right;
}

.accordion-button-active:after {
    content: "\25BC";
}

<button class="accordion-button">
                    Accordion 1
 </button>
<button class="accordion-button accordion-button-active">
        Accordion 2
 </button>
