Fabric js textbox wrap a long word

问题

I am using a customized textbox which should maintain the same width for a textbox while splitting a long word into a new line (I have modified the solution initially proposed by one of the library's maintainers). You can find the code in the following link. The _wrapLine function is overridden.

The problem is, when the word is too long, it splits into lines, but the cursor is not correctly positioned.

Any ideas to fix this?

Thanks in advance
