I'm trying to upload a file with "googleads.png" as filename, and I have an error "Failed to validate file names."

I read this doc : https://docs.microsoft.com/en-us/rest/api/storageservices/naming-and-referencing-containers--blobs--and-metadata
and found nothing about it.
So, why it doesn't work in web interface ? Is it a bug or a constraint ?
Note:
When I change the filename, it works correctly.
If I use the Azure CLI to upload it, it works too.
If I use another image, and rename it to "googleads.png", it failed yet.
