Infinite Sword Glitch

Destroying a slime enemy with Flame Sword and getting grabbed on the same frame will spawn a permanent Flame Sword hitbox in front of Mega Man.  Taking any sort of damage or using Flame Sword again will cancel the effect.  This is currently not useful for RTA, but you can see a video of the glitch here - https://www.youtube.com/watch?v=XLyMGS1ZBIY.
