<sub> tag is ignored in Slide mode

Is this a hackmd.io issue?

• Yes, the bug happens on https://hackmd.io
• No. If it's a self-hosted CodiMD instance, please fire up the issue in the repo of CodiMD: https://github.com/hackmdio/codimd

What's the problem

I want to reduce some text size, in order to make room for an image. I use the <sub> tag, which is correctly rendered in Preview mode. However, in Slide Mode, the tag is ignored, and the text is so large that the image gets pushed outside the screen

Current behaviour

Expected behaviour

The text, which is correctly shown in a small font in the preview area, should be rendered in a smaller font, in Slide mode too.

Environment

I use HackMD on:

Desktop

• macOS
• Browser: Chrome
• Browser Version: 73.0.3683.103

Inizia dalla riproduzione HackMD collegata e confronta il rendering dello stesso contenuto _{in Preview mode e Slide mode. Segui il punto di ingresso del rendering di Slide mode e verifica che anche lì il testo venga ridotto, senza spingere l’immagine fuori dallo schermo.}
