[🐛 Bug]: Edge in IE-mode cannot select dropdown from single-select dropdown menu

What happened?

Dear people of the Selenium community, I’m facing an issue with the Internet Explorer Driver Server and I’m hoping someone knows a way of fixing this or whether this is really an issue with the IE Driver Server and we need to wait for a new version of this driver.

So in short, we had a functioning test automation tool which used an older version of Selenium (3.141.59). A while ago, Internet Explorer was turned off in our work environment, forcing us to switch to Edge. The application we test only works properly in IE or the IE-mode in Edge. Because of this, we upgraded our test automation tool to the newest version of Selenium with the corresponding Internet Explorer Driver Server (at the time 4.3.0.0; but we’ve also tried the newer version (4.5.0.0).
However, we notice that when using the IE-mode of Edge, dropdown menu options can not be selected (our dropdown menu is single select).

The error we get, is: Cannot locate option with value [X], not possible to set this dropdown choice. Is there any way around this issue so that we can still use Edge in IE-mode? We do not have the option to use another browser, as the application is specifically built to function correcly in IE or Edge’s IE-mode (and this will not change in the near future). I’m hoping someone can help, thank you in advance!

How can we reproduce the issue?

Unfortunately I cannot share the code as it contains client-sensitive data.

More importantly, we need a complete way to reproduce the issue, so we can have a look at it.

Unfortunately my colleague who has access to the code, is absent from work at the moment, so I can’t post the info required right now (I can’t post the client URL anyway, but I can post the code and logging info when I receive it).
