x11-toolkits/vte based applications failing to recognize pseudo-terminals on 9.x

[Douglas Carmichael]

To whom it may concern:

When I use terminal applications that utilize the vte widget (x11-toolkits/vte), the pseudo-terminals that they spawn are not recognized by the system. 
For example, when the 'finger' or 'w' commands are used, terminal windows created by said applications do not show in their output.

However, on 8.2, they do.

Please see the attached screenshots for an example.
