JavaScript - diferent execute/load-order in diferent browsers

Does anybody have any idea why the following code will be executed in different order in different browsers? Code is in an external file embedded in a plain HTML page between <body></body> using <script src="js/filename.js"></script>.

document.write("This is the first document.write()");

document.write("<br />followed by a second doc.write with br-element before");

document.write("<br /> and a third one doc.write with br before");

alert("now comes an alert() as fourth (will be expected)");

document.write("<br /> then there will be a fifth doc.write after the first alert");

document.write("<br />and a one more (sixth) doc.write after which an alert will be expected");

alert("the second alert at seventh position");

document.write("<br />and now the eight doc.write after the seventh alert");

Chrome executes the alerts at first followed by the docWrites, Edge execute the first 3 docWrite's, then both alerts and then the other docWrite's (also wrong order). Only Firefox execute this code in the right order.

Same behavior is when I execute similar code in developer tool of the browser(s) for example: write in one line an document.write(); followed by an alert(). Chrome will execute the alert() as first...

Does anyone have any ideas?
