Synopsis in tailtip widget is limited to a certain length

[rehand]

I'm using picocli with JLine3 in version 4.7.5 and there is the following issue:

When using TailTipWidgets the first line shows the synopsis of a command. This line seems to be limited to a certain length, but I was not able to find out how to increase the size. It also doesn't use the number of columns of the current terminal.

E.g. the command default from the parent command testtest shows the following help:
──────────────────────────────────────────────────────────────────────────────────────────────────────────────────────── testtest default [-h] [-u[=<user>]] [-pw[=<password>]]

The command contains 4 options outside an argument group (3 of them with values) and one (exclusive) argument group with an option and a parameter.

@remkop can you tell me how to increase the column width here?
