In the Gnome desktop environment on Fedora 28 Linux (libraries unknown), when I click Activities, go into the Favorites list, and click Show Applications, I see icons with labels. One of the labels says, "Firefox on Wayl..." (suspension points or ellipsis so in original). If that's an ellipsis, I didn't know what it stands for until I Googled it, and going onliine is not always possible. Please show the full label without truncation, even if you have to word-wrap into multiple lines and even if  you have to display fewer icons per page. Or show the full label in a tooltip when we hover.
