the fun part of a developer fixing a bug like this is that the tester has to effectively test a heisenbug If a tester were to verify that Þtestword1 can be commented on, then it changes the state of the database, and they'd have to go to Þtestword2
Right now, a search for Þúsundþjalasmiður results in a 'lower case' suggested þúsundþjalasmiður
In this case it's an entry currently not 'a word' because the like or list function hasn't been applied to it. Liking and Listing words results in the database having to keep track of it as if it were a word.
A tester would have to enter Þtestword1, and verify the fix. Further tests would have to use an incremented test word because in verifying that Þtestword1 works, it's now in the database, so they'd have to use Þtestword2 and so on.
