ID 604264 - The Viewer's 'channel' knob does not resize when cycling through layers with the Page Up/Page Down hotkeys

Problem summary
The Viewer's channel knob does not resize when cycling through layers using the Page Up/Page Down hotkeys.
 
Customer reported version
Nuke 16.0v2
 
Customer reported platform
Rocky 8
 
Steps to reproduce
 
1) Open Nuke.
 
2) Read in a multichannel EXR with some longer channel names. An example is attached.
 
3) Mouse over the Viewer and press Page Up/Page Down to change between different channels.
 
Expected behaviour
The channels knob should resize the knob to show the full channel name, like it does when selecting the channel from the list.
 
Actual behaviour
The channels knob does not resize when using the Page Up/Page Down hotkeys. This means that longer channel names get truncated.
 
Workaround
Unknown.
