Works fine with previous version of EdgeDriver 115.0.1901.183 and below.

Also reported in EdgrDriver repo:

Might be best to downgrade the driver on linux until fix is available.

Hi @tkoukkari! Thank you for reporting this issue. We'll think about what's best to do about it.

Hey @tkoukkari,
Unfortunately, Microsoft only provides the latest stable minor version for each major version of the driver. Thus, if we want to downgrade the driver version, we would need to revert to version 114, which would lead to incompatibility with the browser that currently holds version 115. Lowering the browser version isn't the most optimal solution either, as many users would lose the ability to test their products for compatibility with the latest browser version. Considering the above, the decision was made to wait for a bug fix from Microsoft.

Ok, thanks for looking into this. Let's hope the next version of EdgeDriver fixes the issue.

Hello! It looks like workaround is given in the upstream ticket MicrosoftEdge/EdgeWebDriver#102 (comment) going to close this specific issue as there is nothing actable for us for the time being, as soon as Microsoft releases a fixed version of the driver it will be a part of the next image update automatically, let us know if there are any more concerns.
