[I have used WiFi bridging in Windows 10 to share my WiFi with other devices. This was done on my Mac using Windows 10 on Bootcamp. Specifically, I want to share WiFi to WiFi.
How can I achieve the same on macOS?
Here's what I'm seeing in Internet Sharing:
This all happens inside the "Sharing" pane of "System Preferences":
From my own experience Internet Sharing is not, and has never been, as reliable as it should. Connection coming back and forth is a usual behavior of the service, heavily depending on the usage of the machine which is sharing the internet connection.
Apparently, updating to 10.7.4 makes things even worse.

I assume your question is how to share the WiFi internet connection you have with other devices on a cabled network.
You do this by opening System Prefences > Sharing and selecting Internet Sharing:
For "Share your connection from" choose "Wi-Fi".
For "To computers using" select the network that you want to share it with - usually this is "Ethernet".
This achieves connection sharing by using NAT.
If you actually want to bridge your WiFi connection with a cabled connection, so that devices on your cabled connection would work like they were connected directly to the WiFi, it can be achieved like this:
Open System Preferences > Network.
Click the cog wheel below the device list and select "Manage Virtual Interfaces".
Click the plus button and select "New Bridge".
Select "Wi-Fi" and the network you want to share it with - usually this is "Ethernet".
Click Create.
