Link to set a theme as default for a domain is missing domain_config_ui_domain querystring

Needs a test.

Hi guys, any updates here?
Can somebody check my changes?
Thank you in advance

Patch looks good and there is a test! Re-queuing the test bot.

It's a shame there is no way to alter the theme operations except through the page preprocess, but that's a core issue.

This needs to be against the 2.0 branch.

@Igor Mashevskyi The MR will need to be redone against 2.0.x.

Despite of all the appreciated hard work in here I - sorry- cannot reproduce the issue.

Summary states:

If I click the Set as default link the theme is incorrectly set as default for all domains instead of just for the example domain.

This is not correct, at least not for latest dev and latest beta. It is correct that it "feels as if it would be set for all domains" because the selected domain jumps out of the select box by the page refresh on save, which is caused by another (not yet reported) issue: "select box does not keep selected domain after page refresh". But the setting is correctly made for the previously selected domain. At least on our tests here. You can circumvent this behaviour by selecting "remember last selection" in domain form settings.

So we maybe need to further investigate here before rerolling and committing to "not fix something which is not broken". Would recommend to collect more reports on this.
