see this issue for example:
It actually does not work in any wizard so every
developer would need to fix it in every panel
(something like calling requestFocus in addNotify).
Yes, I'll try fix it for next release cycle. Wizard will request focus
for the first focusable component of being opened panel.
Fixed in WizardDescriptor, rev 1.93 with an another issue.
verifying because issue 31086 was veryfied.
