You should listen to the input & change event instead of the keyup event. This approach ensures that the functionality works even when text is pasted from the clipboard, as shown below:

document.getElementById("search").addEventListener("input", e => {
    const query = e.target.value.toLowerCase();
    for (const tr of trs) {
        tr.style.display = tr.innerText.toLowerCase().includes(query) ? "" : "none";
    }
});
document.getElementById("search").addEventListener("change", e => {
        const query = e.target.value.toLowerCase();
        for (const tr of trs) {
            tr.style.display = tr.innerText.toLowerCase().includes(query) ? "" : "none";
        }
    });
