How can I make this SVG polygon "wedge" always have 45 degree ends?

Question

I'm trying to make this wedge shape has 45 degree angles at both ends.

As the size of its containing div changes, or the page is zoomed, that angle changes:

Here's my (abbreviated) code:

<div class="relative">
  <svg class="h-16p top-0 left-0 absolute w-full fill-current" viewBox="0 0 100 4" preserveAspectRatio="none">
    <polygon points="0,0 100,0 95,5 5,5" />
  </svg>
</div>

I'm using tailwindCSS - for those not familiar those classes translate to:

position: absolute;
width: 100%;
fill: currentColor;
height: 16px;
top: 0px;
left: 0px;
