#Needs subsystem maintainer review

For anyone who needs it, this is #106 rerolled for 10.2.x.

Seems the title update and issue summary update are still needed.

Also fixes should be in MRs vs patches.

Finally I gave up the hope that this will ever be finished by anyone (including me). So maybe we should better put our time into implementing a contrib solution?

Maybe in https://www.drupal.org/project/theme_tokens → ?
Seems there are enough people here to do that...

Some fields in Core override the default maxlength attribute up to 1024 characters. There is no reason to not do so in this case.

Yes, but these fields are using a different field widget. I think that a new field widget needs to be created and associated with the core textfield. The link-url form field would then use textfield and the new widget.

The test is failing because there are in fact classes in the page source named 'messages' which have nothing to do with errors.

But the increased maxlength property does not prevent link text > 128 characters from being chopped off at 128. I also tried adding a size property and setting that to > 128 characters. But that has no effect on the textbox either.
