Search includes extra items when lists are updated

Steps to reproduce

Open two browser windows to same blank document.
Add item with a due date.
Search for a range including the due date item.
Add a new, non-due-date item in the non-search window.
Item shows up in the search window.

Expected result

Search automatically updates with the specified filter. The non-date item should not appear in the search results.

Actual result

Non-matching items appear in the search list. Even when selecting the search text and hitting ā€˜enterā€™ the results are not properly updated.

Environment

Chrome browser. MacOS.

Notes

I generally keep a couple windows open to my big document of next actions. One has the search: within:7d OR within:-12m so I can keep track of all the important things that must get done. But this doesnā€™t really work when the search filter includes newly entered items elsewhere in the document.
