Missing info icon in Block Editor

Hi,

I just noticed that the small i in a circle info icon has vanished from my block builder. I've checked preferences to see whether I had somehow activated a reduced set of icons but that checks out ok.

There have been both WordPress and GeneratePress updates recently so I'm thinking one of these could be the cause.

I use this icon a lot to check my word count. However, I can still check my word count by clicking the Document Overview icon and then click on Outline but the other way was much quicker, with just a single click.

The following image might help explain what I mean.

Can you possibly help with this issue?

Cheers,

Adrian.
