Javascript generate/save string to file but encountering 65535 character limit

Using the following code from Using HTML5/JavaScript to generate and save a file :

function download(filename, text) {
    var pom = document.createElement('a');
    pom.setAttribute('href', 'data:text/plain;charset=utf-8,' + encodeURIComponent(text));
    pom.setAttribute('download', filename);

    if (document.createEvent) {
        var event = document.createEvent('MouseEvents');
        event.initEvent('click', true, true);
        pom.dispatchEvent(event);
    }
    else {
        pom.click();
    }
}

download('test.txt', 'Hello world!');

I also used a blob but no luck:

var fileContent = String.raw`test`;
var fileName = 'sampleFile.txt';

const blob = new Blob([fileContent], { type: 'text/plain' });
const a = document.createElement('a');
a.setAttribute('download', fileName);
a.setAttribute('href', window.URL.createObjectURL(blob));
a.click();

I am encountering a limit on downloading a string to a file through a hyperlink. I have found in Chrome that if the amount of characters exceed 65535 the hyperlink disappears or on firefox, a 0 bytes file is downloaded.

Is there a way to circumvent this limit? Or perhaps a different way in pure javascript/html to download the file where this limit doesn't exist or is increased?
