Rendering in close corners

[katexochen]

Sometimes corners that are close to each other cannot be rendered as desired:

The following is kind of expected:

+----------+
|  PCRn    |
+----------+
+----------+
| Nonce    |
+----------+

It would be great if using other corners would not connect the two boxes:

+----------+
|  PCRn    |
'----------'
.----------.
| Nonce    |
+----------+

but it currently renders the same as with +
