[BUG] Content mis-alignment with Image Slider upon refresh

[pxamike]

Describe the bug
Possiby related to #54 . Looks like a race condition as it only happens sometimes, where the content inside a slide is misaligned. It could be that there's js that runs based on metrics before the css is applied (that modifies some metrics).

To Reproduce
Steps to reproduce the behavior:

1. Go to: https://demo.t3kit.com/content/dynamic-content/image-slider
2. Hard-refresh until the text inside the first slide is misaligned.

Expected behavior
The content inside the slide should never be misaligned.
