How to reproduce

• Open the repository workspace (any workspace with 3 potential columns can do)
• Reinitialize the workspace
• Open the "console" tool, this opens the result tool in the right column
• EnLaRgE YouR right column (without touching the two others)
• Refresh the page

The layout bugs, as shown in the screenshot: the right column is initialized with the right size, but the left column is very small.
