Get random sorting of array after dropdown is selected

Question:
I have this website im currently working on
https://lavster.wixsite.com/website
Once the website loads, the list of vlog sites randomly sorts to avoid bias to new or alphabetically sorted names. But I want to try and get it to sort the data again after a filter is in place, for example selecting Vegas from the drop down.

import wixData from 'wix-data';

$w.onReady(async function () {
    // Initialize the repeater with all items
    let res = await wixData.query("VegasVlogs").find();
    let allItems = res.items;

    // Initialize the repeater with shuffled items
    let shuffledArray = shuffleArray(allItems);
    $w('#repeater7').data = shuffledArray;

    // Add an event handler for the dropdown selection
    $w('#dropdown1').onChange((event) => {
        console.log('Dropdown selection changed:', event.target.value);
        const selectedTag = event.target.value; // Get the selected tag

        // Filter the items based on the selected tag
        const filteredItems = allItems.filter(item => item.tags.includes(selectedTag));

        // Shuffle the filtered items
        const shuffledFilteredItems = shuffleArray(filteredItems);

        // Update the repeater data with the shuffled filtered items
        $w('#repeater7').data = []; // Clear existing data
        $w('#repeater7').data = shuffledFilteredItems; // Update with filtered and shuffled items
    });
});

function shuffleArray(dataArray) {
    for (let i = dataArray.length - 1; i > 0; i--) {
        let index = getRandomIndex(0, i);
        const temp = dataArray[i];
        dataArray[i] = dataArray[index];
        dataArray[index] = temp;
    }
    return dataArray;
}

function getRandomIndex(min, max) {
    return Math.floor(Math.random() * (max - min + 1)) + min;
}

What are you trying to achieve:
So I have managed to get the code working that randomly sorts the results in a repeater once the website is loaded, however when I select a filter from the tags in the dropdown, the order of the filtered results in the repeater is just how they have been entered into the CMS, I have tried many different combinations on the OnChange code for the dropdown but it doesnt ever sort it.

I have attached the code above that i have tried so far.

What have you already tried:
Different on click commands to try and get the data randomly sorted

Might want to try some of the implementations here for randomizing an array, they’re slightly different, especially when it comes to generating the random index:
