The seagulls went back early to behead Kyle Bartley.
Brighton reacted almost immediately after winning a penalty thanks to a VAR call treating Okay Yokuslu in the area, but Pascal Gross hit the resulting free kick against the crossbar.
But Graham Potter thought they would have equalized when a quick free kick from center-back Lewis Dunk caught goalkeeper Sam Johnstone off guard.
Confusion ensued as referee Lee Mason and his VAR team struggled to determine whether or not the referee whistled before or after kicking the ball.
After Mason initially appeared to have achieved the goal, he thought for a long time and even went to his pitchside monitor before rejecting the strike.
Brighton continued to press for an equalizer after the break, however, and had another gold-plated opportunity to hold the Baggies back when Gross fell deep into the box in the second half.
This time Danny Welbeck stepped forward, but he also saw, quite unbelievably, how his attempt hit the woodwork.
The result leaves Brighton four points ahead of the drop zone. Relegation rivals Fulham and Newcastle United both hold a game against Graham Potter’s men.
But what about transfers?
Here we take a look at the rest of the Premier League transfer talk off the internet, while Brighton’s top target is some flashy deals:
