Description Kent Tamura 2011-05-18 23:58:41 PDT 
1. Load data:text/html,aaa <details open>bbb <summary>ccc</summary> ddd</details> eee
2. Select all text (⌘-A / Ctrl-A)
3. Copy (⌘-C / Ctrl-C)
4. Paste on a plain text box

Expected:
 The pasted text should be "aaa ccc bbb ddd eee" because it's the visual order.

Actual result:
 The pated test is "aaa bbb ccc ddd eee".

I don't think this is so severe.

Reforming tree: Pushed this down to the flattened tree family.

I am able to reproduce this bug in Safari 15.6 on macOS 12.5 using mentioned test case converted into JSFiddle:

Link - https://jsfiddle.net/yntdab40/show

Selecting any text and then doing CMD + A then CMD + C and then copying here shows this for Safari 15.6 and Firefox Nightly 105:

aaa
bbb 
ccc
ddd
eee

While for Chrome Canary 106, it shows this:

aaa
ccc
bbb dddeee
