In the video Lilac is at full health and has a Wood Shield. She is launched into the final area before the boss at a moderately high speed. As she passes above the 6 health petals her trajectory is changed, so one of the petals seemingly passes right through Lilac, failing to connect, and eventually flies away outside the screen.
Only 5 "+crystal" icons appear on the upper-left of the screen, confirming that the 6th petal is never obtained.
The other possible reason for this bug to happen is a flaw in hit-confirming, when the high speed of the petal causes its hitbox to change its position too much between the frames and go right through the character without colliding with thier hitbox on the way.
Submitter: SPeCtator It looks like in some rare cases the pickup attraction fails to properly bring a pickup to the player character.
Can be observed in this video (at 6:38):
