Striking from inside a tank means nothing...snakes don't identify you visually thru the glass- they see the motion & think either food or predator...nothing personal.
I doubt she'll mind if your handling continues as before since she's a good eater & already knows you- she's not brand new.
The MAIN thing is to secure your tank!!! You are very lucky to have found her quickly this time...king snakes hide very well, & you might not get her back next time,
or she might get injured when loose. Please be responsible & prevent any & all escapes.
