QMessageBox doesn't want to resize according to title length (probably same happened to QInputDialog).

```c++
QMessageBox::warning(this, tr("Tracker editing failed"), tr("Invalid URL"), QMessageBox::Ok, QMessageBox::NoButton);
```

Appending `\t\t` works as a workaround, or I could just make title shorter or remove it completely.
