Repositories view loses selection

[rherrmann]

To reproduce, configure the workspace to include a remote repository, for example, the Bndtools Hub repository from https://raw.githubusercontent.com/bndtools/bundle-hub/master/index.xml.gz and open the Repositories view.

Enable the workspace refresh option in Preferences > General > Workspace > Refresh using native hooks or polling.

Expand the Bndtools Hub item and select one of its children. Wait a little until some job is executed and the repositories view loses its current selection.

Bndtools version is 3.4.0.DEV 2017-01-17
