Temporary workaround:

import ipywidgets as ipw
from IPython.display import HTML, display

%%html
<style>
.text-after-eq {
    left: -5px;
}
</style>

h1 = ipw.HTMLMath('$\sin(x^2) + \sum_{n=0}^\infty \left ( \cfrac{1}{n} \\right )$')

h2 = ipw.HTML(', мм',layout=ipw.Layout(align_self='center'))
h2.add_class('text-after-eq')

ipw.HBox([
    h1,
    h2
])

HTML('$\sin(x^2) + \sum_{n=0}^\infty \left ( \cfrac{1}{n} \\right )$, мм')
