**List of steps to reproduce** (step by step, including full links if applicable):

Visit Sigmaster's conjecture#Elementary examples, Nilpotent matrix#Example 2, or De Moivre's formula#Formulae for cosine and sine individually on Wikipedia in either Chrome or Edge (or any other Chromium-based browser)

**What happens?**: Some digits (such as the zero in the lower-right corner of matrix B at Nilpotent matrix#Example 2 and one of the digits equal to 4 in the number 61218182743304701891431482520 at Sigmaster's conjecture#Elementary examples) are not displayed correctly. If you zoom in at Sigmaster's conjecture#Elementary examples, the following digit 3 and the second-to-last digit 2 (between 8 and 5) are not displayed correctly. If you zoom in once more, then all digits would appear correctly.

At De Moivre's formula#Formulae for cosine and sine individually, some characters are also not displayed correctly, as reported by NadVolum at the Wikipedia link at the bottom.

**What should have happened instead?**: All characters appear correctly.

**Software version (if not a Wikimedia wiki), browser information, screenshots, other information, etc**:

Using Microsoft Edge on Windows 10 (version 94.0.992.38 if that matters)
