Lipgloss doesn't split on whitespace

[CalebJohnHunt]

I'm just trying to use Lipgloss to limit my text's width like so:

wrapper.Copy().Width(wrapper.GetWidth() - 10).Render(text)

I have a var wrapper lipgloss.Style, I copy it, set its width to its old width minus some constant, and render that text.
I expect it to always split on whitespace (when possible), but I am occasionally finding weirdness such as the following:

I use a Moonlander at home and I don't ever use the red thumb button or the bottom
one because of how uncomfortable it is (and having rewritten this now, I'm        
considering swapping the top right thumb button - return - and the middle left thu
mb                                                                                
button - backspace - because i use backspace so much more).                       

(NB trailing spaces have been left in for accuracy)
The split between "I'm" and "considering" is totally reasonable, but what I don't understand is the split between "thu" and "mb" and newline after "mb". Since "...and the middle left thumb" is too long for the width (which is correct), I would instead expect

I use a Moonlander at home and I don't ever use the red thumb button or the bottom
one because of how uncomfortable it is (and having rewritten this now, I'm        
considering swapping the top right thumb button - return - and the middle left    
thumb button - backspace - because i use backspace so much more).                 

And to be clear, Lipgloss often is splitting on the whitespace, but just rarely (about 1 in 15 cases for me) it splits in the middle of a word.

Any thoughts why? Am I missing a setting?

Additional info (will be updated if more is brought up):

• Lipgloss version: v0.8.0 (though I was finding the same thing on older version)

• Go version: go1.21.0 linux/amd64
