Twenty Seventeen: Header image zooms in when scrolling down on Mobile Safari

[mrfoxtalbot]

Steps to replicate

• Open TwentySeventeen demo site in Mobile Safari (​https://twentyseventeendemo.wordpress.com).
• Watch the header image as you scroll down the page.

(Note that this only seems to happen in Mobile Safari, and doesn't appear in Chrome/Safari on the desktop even with a small window)

The header image zooms in slightly when scrolling down, providing a jarring experience for the viewer. The header image should not change size when scrolling.

I can't seem to see this as an issue. Can you please check to see if this is resolved? For now I am going to add the keyword 'close' as a recommendation. If other information comes up we can also remove it, thank you everyone for collaborating so far.

I can still replicate this on an iPhone 12 (I reproduced it on an actual phone even though the recording is from a simulator):

Oh thank you @mrfoxtalbot let me remove the close key work and put back this into testing.
