Can’t upload SVG

I gave Admin unrestricted SVG upload capability, and could not upload images when working with other plugins.

What was happening: Using WP SVG Images with Stripe Payments plugin. I was trying to add a thumbnail to a new product but the SVG image would not upload.

Since then: I installed another SVG plugin. I went back to recreate the problem and, even after deleting the other SVG plugin, I was able to upload the SVG thumbnail into a product using SVG Payments plugin. Go figure.

I will try to recreate the site from backup to see if I can recreate it.

The issue was first mentioned in a review, moving it to support to try and figure it out (sorry for the delay, had to get the site up and running)
