Improve layout for checkboxes

[Markus-Elfring]

I am trying the software “birt-report-designer-all-in-one-4.9.0-20220315-linux.gtk.x86_64.zip” out.

I observed the following display result which I find questionable.

How should be achieved that the labels will be completely displayed for such checkboxes? 🤔

This is related to #905. The reason (and if it exists) the solution is probably the same.

@priytosh-tripathi Is this something for you?

Sure @wimjongman , I'll take this up. Please assign it to me!

@priytosh-tripathi Are you using linux? Otherwise you won't be able to reproduce the issue.

I have all three platforms(mac,windows,Linux) available in personal possession. I'll be good to go for any required platform. 😊
