Not the load method, but implementing a session class as a Singleton looks wrong to me. The whole point of a session is to have multiple, one for each user.
However they have some strict rules on what is allowed so it may not be suitable for open source projects. Two problematic ones are: 1) The poster must be the author/owner of the code. You, for example, can't post code that someone else has written. 2) All code that is to be reviewed must be included in the post. You can't just link to a repository.
Although this seems like the laziest variant. It shouldn't be that complicated to redesign the navbar allowing two line text and hyphenation of the text.
