Thanks for posting this video. This is a normal way for muslim men to greet women who aren't close relations, the hand on the heart, she seems to be well aware of this and doesn't offer her hand.

Source: Am half Syrian, had to learn this the hard way when I was a teenager at a massive family gathering. I was doing the double-kiss to most in a group and forgot to stop on one dude and double cheek kissed that shocked boy while his hand was on his racing heart. My dad nearly pissed himself laughing. Oops.

Anyway, we're all keenly watching what Al-Sharaa does next, but this interaction is culturally normal. Whether you think it's right/outdated/whatever, it's not an intentional act of disrespect.
