A problem about visualization when running demo

[hengrui0516]

First of all, thank you for your excellent work. But when I run the demo: https://github.com/CyberAgentAILab/layout-dm/blob/main/notebooks/demo.ipynb, I meet a confused problem as follows:

As you can see, I use a hand-made layout to test, 2 regions overlap. But they won't overlap by math computation in theory.

I only run the first and the third cell. The second cell can be ignored.

It is due to the decode accuracy of the tokenizer.
