Truncation and redraw issues with menu for selecting context.

[GrahamDumpleton]

What steps did you take and what happened:

Use a current context which has a long name. Use a narrower width browser window, not full width on a 27inch plus monster display. :-)

The menu for changing the current context top right of Octant will show the name of the current context, but due to limited width of the browser window, this will be truncated.

More of a problem is that if you click on the menu drop down, the drop down menu is not being right side flushed to browser, and instead pushed the content to the left, leaving a blank section down the right, with the menu overlaid.

Deselect the menu and it vanishes, but you need to horizontally scroll the page content back to the right to see it all properly as left hand side pushed out the left side of the window.

What did you expect to happen:

Shouldn't force horizontal scrolling and menu should fall to left of the drop down instead. Would be nice to handle better the truncation of names.

Anything else you would like to add:

Nope.
