@rhamilto anything we can do about this?
In tinkering with it, I don't see an immediate fix that retains the scrolling behavior we've established for the inner page contents. Simply making the left sidebar scrollable vertically means the dropdown menus aren't visible (they are positioned outside the width of the sidebar). :/
This was fixed by https://github.com/openshift/origin-web-console/pull/663.
This has been merged into ocp and is in OCP v126.96.36.199 or newer.

left navigation menu bar can not scroll
Not seen the scroll bar as PR https://github.com/openshift/origin-web-console/pull/663 on Chrome 52 and Firefox 45, also menu navigator tree is not like the screenshot in PR, please see the screenshot in the new attachment "left navigation menu bar can not scroll"
Tested on openshift v188.8.131.52
The screenshot in https://github.com/openshift/origin-web-console/pull/663#issue-182559002 documents the fix included the PR. The second screenshot  in the PR is a hypothetical fix that is not included in the PR.
Please note the bug only exists under the following conditions:
| Zoom level | Viewport height | Viewport width |
| ---------- | --------------- | -------------- |
| 0 | <= 440px | >= 768px |
| 1 | <= 484px | >= 844px |
| 2 | <= 552px | >= 960px |
We will likely need to unfix the left navbar to ensure this bug never happens given the left navbar is configurable.
Since Steve has been working on the nav changes for 3.7 that will address this bug, I'm reassigning it to him.
The updated console vertical navigation now displays a scrollbar when content is taller than the viewport. see screenshot

Vertical nav bar
Cause: The left navigation column did not support vertical scrolling.
Consequence: When browser viewport is less than 440 pixels tall and wider than 768 pixels the bottom left navigation link was not accessible.
Fix: The new left navigation column markup supports vertical scrolling.
Result: All left navigation links are accessible at all browser viewport sizes and zoom levels.
