Inline toolbar with more than 5 buttons covers selected text

[indevhub]

using "mui-rte": "^2.0.1"

By default, the inline toolbar width is set to only allow 5 buttons across before creating a second row. Unfortunately this second row then covers the text that has been selected and prevents a user from "triple clicking" to select a whole paragraph.

What is the recommended way to set the inline toolbar width so that it can hold more than 5 buttons on the first row?
