The problem is not with closing the laptop lid, but when the computer goes to the Suspend or Hibernate state. The problem seems to be related to how long the laptop has been in one of these two states. The longer the laptop is in the Suspend or Hibernate state when WFX4 is Enabled, the longer it appears to take to recover, but it does seem to recover eventually.
I have some really coarse timing information for recovery from the Suspend state. With WFX4 Disabled and the laptop in the Suspend state for 5 minutes, hitting the Shift key brings up the logon prompt in about 1 second. With WFX4 Enabled and the laptop in the Suspend state for 5 minutes, hitting the Shift key brings up the logon prompt in about 6 seconds. Based upon these admittedly coarse measurements, a laptop that has been in the Suspend state for 8 hours would take about 8 minutes to eventually "catch up". Small wonder that users are power cycling their laptops!
