In the dashboard, if I open a pool's disk details and do the same on other pool, the first frame gets partially updated with the info of the second chosen disk.
Steps to reproduce the bug in my system setup:
1) Open /ui/dashboard, click Pool_raidz "Data: 1 vdev"
2) click the disk list
3) click "ada0" device
4) the correct disk details appear ("Device Details" and "Advanced Details")
5) click Pool_stripe "Data: 2 vdevs", click the first disk 
6) click "ada4" device
7) "Disk details" remain unchanged on Pool_raidz's frame but the "Advanced Details" are replaced by ada4 device's values
If "Pool_raidz" list is navigated back and one of the devices is selected, the "Pool_stripe" disk advanced details is also replaced.
 the "Data" list on stripes (such as in my "Pool_stripe" pool) should show some information about the disk. The way it is listed now makes it impossible to tell one disk from the other(s).
