ifthe names in the sidebar for the junit-realtime reports are way to long to fit into the space and this then provides a very ugly UI.
This is likely a generic Jenkins issue. I wonder if the CSS can be modified to truncate the text and expand it on hover or something. (or Jenkins introduces a new shortName / longName for the sidebar actions)
if a picture paints a thousand words here are 1000 more words.
it solves one part of the issue but introduces another so I don;t think it is closed and the original fix is incomplete.
A long name/whatever is truncated and is never expanded so you can not see what the original should be ever. this should be and expand on hover, and abbrev or something but brutally truncating and not expanding is to me not a good UX
