Tooltip for partner logos

Most logos have company name but some logos like FZ would need a tooltip to show who they are. Some logos are hard to read like nextcloud & I am using FHD screen. I suspect they are barely readable on 4k.

look fine. MariaDB is a bit sketchy. I guess the logos have been provided by the partners themslef and have been cleared off?

This is how most sites show logos nowadays.
