Replaced image maintains the old URL

I’ve got a logo image in my Assets that I don’t actually use on my site, but I use it in my email signature HTML. I’ve had a need to shorten the filename of the logo image, so I deleted the one in the Asset Panel, and uploaded a new file with the shortened filename. However, Webflow is maintaining the old filename in it the URI for the file. Nothing I have done forces Webflow to give the new file a URI with the new filename.

The original file was named - ‘ci_logo_email.png’
The new file is named - ‘logo.png’

yet the URI for the image is still -

Is Webflow somehow able to see that it’s actually the same graphic, but just renamed?

Yep. Change the bits a little.
