fieldset tag and Inline forms

[mdsupport]

As seen in the image below, BS4 does not seem to like <fieldset> tag with the inline layout.
Is that tag important for the code generated by this library?

It appears to be known flexbox issue due to the treatment of the fieldset tag by different browsers. Suggested workaround is to include a div tag as immediate child as shown in this codepen.

Will this affect the functionality?
