Ext 4.1.0-gpl: tabpanel won't show chart without a height set
I'm actually having this issue under 4.0.7 but can reproduce it using extjs example code from 4.1.0. I've been having to specify a height to get a chart to show in a tab, but that in turn causes a problem in that if the browser/viewport gets resized, the chart doesn't.
To see the issue in 4.1.0 I made very minor modifications to a couple of files in examples/tabs code:
Refer to example-data.js at the top of tabs.html
Replaced the second tab with the first chart from examples/charts/Charts.js
Fiddled with layout: fit and height properties for the chart; the former seems to have no effect
Below are the diffs and screenshots a) when height is not specified and b) when height *is* specified
