Class selectors - changed?

Hello,
Did the class selectors get changed on softr in the past 24 hours? Both the below used to wrap the action button dropdown menu text (as it disappears and is not readable without wrapping)

button.MuiButtonBase-root.MuiButton-root.MuiButton-contained.MuiButton-containedPrimary.MuiButton-sizeMedium.MuiButton-containedSizeMedium.action.MuiBox-root.css-z0xzfk {
white-space: pre-wrap;
}
a.MuiButtonBase-root.MuiButton-root.MuiButton-contained.MuiButton-containedPrimary.MuiButton-sizeMedium.MuiButton-containedSizeMedium.action.MuiBox-root.css-z0xzfk {
white-space: pre-wrap;
}

Now they seem to be css-o9hp6b?
