LEDE 17.01-rc1 r3042: Changing LAN static IP address doesn't force new DHCP addresses LEDE

Install LEDE 17.01-rc1 r3042 on both Archer C7 and Netgear WDR3400:
I log in successfully to 192.168.1.1, enter a password, then use web gui to change static IP address of the LAN interface (to 192.168.250.1)
The web gui shows a spinner, but (of course) doesn’t reconnect to the router, since the address has changed.
I waited a while (60 seconds?) and my OSX box doesn’t notice that the Ethernet has a new IP - it’s still on 192.168.1.x
If I disconnect the Ethernet cable and reconnect immediately, within a second or two, OSX detects the new (correct) IP address in the correct 192.168.250.0/24 subnet.
I think OpenWrt/CeroWrt used to recover without requiring a disconnect of the Ethernet cable (but could be mistaken).
This isn’t a severe problem, because disconnecting/reconnecting the Ethernet is a perfect workaround.
