Selecting text in a terminal makes the selection disappear at first
The affected version: xfce4-clipman-plugin-1.6.6-1.fc39
When selecting text in a terminal, the text is copied to the clipboard and can be pasted correctly, but the selection itself disappears. When trying to select the same text again, the selection persists and no new (duplicate) entry appears in the history. In fact, any text at all inside the terminal can be selected and as long as it's identical to the last entry in the history, the text stays selected. Otherwise a new entry is added and the selection is "consumed".
I've seen this happen only when selecting text inside a terminal. Selecting text inside Firefox works as expected. Clipman is configured to "sync mouse selections".
The behavior differs from older versions of Clipman that I've used and seems unintended.
