2. load https://bugzilla.mozilla.org/chart.cgi?category=Plugins&subcategory=Xine&name=2210&label0=Quake+Live&line0=2214&label1=QuickTime+(Apple)&line1=2190&label2=RealPlayer+(Real)&line2=2192&label3=Shockwave+(Adobe)&line3=2194&label4=Silverlight+(Microsoft)&line4=2196&label5=Silverlight+(Mono)&line5=2198&label6=VeohTV+(Veoh)&line6=2200&label7=Viewpoint+Media+Player&line7=2202&label8=VLC+(VideoLAN)&line8=2204&label9=Windows+Media+Player+(Flip4Mac)&line9=2206&label10=Windows+Media+Player+(Microsoft)&line10=2208&label11=Xine&line11=2210&datefrom=2010-01-01&dateto=2011-01-01&action-wrap=Chart+This+List
3. open a new tab with the same url
4. click taller a couple of times until you reach:
https://bugzilla.mozilla.org/chart.cgi?category=Plugins&datefrom=2010-01-01&dateto=2011-01-01&label0=Quake%20Live&label1=QuickTime%20(Apple)&label10=Windows%20Media%20Player%20(Microsoft)&label11=Xine&label2=RealPlayer%20(Real)&label3=Shockwave%20(Adobe)&label4=Silverlight%20(Microsoft)&label5=Silverlight%20(Mono)&label6=VeohTV%20(Veoh)&label7=Viewpoint%20Media%20Player&label8=VLC%20(VideoLAN)&label9=Windows%20Media%20Player%20(Flip4Mac)&line0=2214&line1=2190&line10=2208&line11=2210&line2=2192&line3=2194&line4=2196&line5=2198&line6=2200&line7=2202&line8=2204&line9=2206&name=2210&subcategory=Xine&action=wrap&width=600&height=650
5. switch between the two tabs

expected results:
as you make the chart taller, the number of vertical hashmarks should increase, showing more intermediate values

actual results:
the spacing increases but the number of vertical hashmarks doesn't change, which makes the graph less helpful
