Context: Google Docs uses a `b` element to wrap their content with the document id when copying content e.g. `<b id="docs-internal-guid-[uuid goes here]">`. When creating a Google Doc with an empty line or empty list item as the first element, Safari converts this element into a style and strips other elements. I have attached a very simple HTML reproduction case with the following example: Input (clipboard content): <b data-important-attr="xyz"> <ul> <li></li> <li>text</li> </ul> </b> Output (result from paste): <br> <div> <span style="font-weight: bold;">text</span> </div> Adding any content into the first list item results in the expected output: Input (clipboard content): <b data-important-attr="xyz"> <ul> <li>text</li> <li>text</li> </ul> </b> Output (result from paste): <b data-important-attr="xyz"> <ul> <li>text</li> <li>text</li> </ul> </b> It is also worth noting that this occurs even without the wrapping `b` element: Input (clipboard content): <ul> <li></li> <li>text</li> </ul> Output (result from paste): <br> <div>text</div> 1790002 1 webkit-bug-importer 2021-09-02 18:01:01 -0700 <rdar://problem/82701564> 436596 2021-08-26 17:59:16 -0700 2021-08-26 17:59:16 -0700 A simple HTML file to replicate the bug content_loss.html text/html 802 james PHA+UGxlYXNlIGNsaWNrIGFueXdoZXJlIGluIHRoZSBwYWdlLCBoaXQgQ01EL0NUUkwrQywgdGhl biBwYXN0ZSBiZWxvdy48L3A+CjxwPlRoaXMgYWRkcwogIDxwcmU+CiAgICAmbHQ7YiZndDsKICAg ICAgJmx0O3VsJmd0OwogICAgICAgICZsdDtsaSZndDsmbHQ7L2xpJmd0OwogICAgICAgICZsdDts aSZndDt0ZXh0Jmx0Oy9saSZndDsKICAgICAgJmx0Oy91bCZndDsKICAgICZsdDsvYiZndDsKICA8 L3ByZT4KdG8gdGhlIGNsaXBib2FyZDwvcD4KPHNwYW4gc3R5bGU9ImNvbG9yOnJlZCIgaWQ9Im91 dCI+PC9zcGFuPgo8c2NyaXB0PgogIGRvY3VtZW50Lm9uY29weSA9IGV2ID0+IHsKICAgIGV2LmNs aXBib2FyZERhdGEuc2V0RGF0YSgndGV4dC9odG1sJywgJzxiIGRhdGEtaW1wb3J0YW50LWF0dHI9 Inh5eiI+PHVsPjxsaT48L2xpPjxsaT50ZXh0PC9saT48L3VsPjwvYj4nKQogICAgZXYucHJldmVu dERlZmF1bHQoKTsKICAgIG91dC50ZXh0Q29udGVudCA9ICdDb250ZW50IGNvcGllZCB0byBjbGlw Ym9hcmQsIG5vdyBwYXN0ZSBiZWxvdyc7CiAgfQo8L3NjcmlwdD4KPGRpdiBjb250ZW50ZWRpdGFi bGU9InRydWUiIHN0eWxlPSJib3JkZXI6IDFweCBzb2xpZCByZWQ7Ij5QYXN0ZSBpbnRvIGhlcmU8 L2Rpdj4KPHA+T2JzZXJ2ZSBTYWZhcmkga2lsbHMgdGhlIHdyYXBwaW5nIGIgZWxlbWVudCBhbmQg dGhlIGxpc3QuPC9wPgo8cD5FZGl0IHRoaXMgZmlsZSB0byBhZGQgYW55IGNvbnRlbnQgdG8gdGhl IGZpcnN0IGxpc3QgaXRlbSBhbmQgdHJ5IGFnYWluLCB0aGUgY29udGVudCBpcyByZXRhaW5lZC48 L3A+Cg==
