I found a way to get out of bounds in the Black Widow fight. Fall towards the bottom, and do full backjump wall jump by using your trion shot, then jump again. Make sure to hold left the entire time. For good measure, spam jump after doing so. If you do it correctly, you'll be above the Black Widow fight. Do a full jump in place for good measure, then walk left until you fall off. Once you fall off, hold right to slide down the wall and grab the ledge towards the bottom. You can then clip inside the boss fight and do an entire cycle without Black Widow being engaged. After that first cycle however, she is invincible, so you have to hit the cutscene trigger to continue.

(by the way, the trigger for exiting this part of the level doesn't exist until you defeat Black Widow, so you can't just skip the entire boss fight unfortunately)

incredible, you've been on a roll with all those lately
