Public bug reported:

Google Chrome has long process names. By long I mean hundreds and
hundreds of characters wide (see picture). Without knowing this I
unsuspectingly double-clicked the process name column edge in the
processes tab, and ended up with a column that stretched far, far to the
right. The only way to get back to normal was to scroll to the far right
and tediously grab the column and shrink it manually over and over until
it got back to normal.

Before doing that I tried double-clicking again to try and make it
shrink to its smallest size -- that didn't work. I generally tend to
expect the reverse operation to work when working with UI. Open-Close,
Expand-Collapse, Show-Hide, etc.

After doing that I -- unfortunately -- tried to disable the process name
column in the column context menu (right click). That made everything
worse. Another column took over the super wide column that previously
held process names, and pretty much every other existing column
seemingly disappeared from the table. After some head-scratching I
figured out that all other columns had collapsed into zero width.

I tried restarting the application -- didn't work; it had saved my
column setup.

Adjusting some column widths went from a simple task to becoming a real
chore.


Expectations:
I expected to be able to collapse the column the same way I expanded it. I also 
expected all other columns to keep their own sizes when disabling/hiding a 
column. In hindsight I now also expect column expansion to have some kind of 
sanity check.


Note: 
I was positive that I had included the scroll bars in the screenshots, but 
apparently they timed out and disappeared, so the pictures kind of fail to 
illustrate the extent of the column width.
