Updating a variable interpolated into a MathJax equation scrolls notebook

[mossr]

When string interpolating a variable into a MathJax equation in Markdown, whenever the variable is changed (thus updating the MathJax) the notebook window scrolls up one tick.

Notes:

• Only happens when there is other cells below
• Only happens within MathJax, normal string interpolation in Markdown does not scroll
• Not specific to @bind, bug is also present when just modifying a variable in a cell (@bind is just easy to play around with it)

Here's a MWE:

### A Pluto.jl notebook ###
# v0.11.14

using Markdown
using InteractiveUtils

# This Pluto notebook uses @bind for interactivity. When running this notebook outside of Pluto, the following 'mock version' of @bind gives bound variables a default value (instead of an error).
macro bind(def, element)
    quote
        local el = $(esc(element))
        global $(esc(def)) = Core.applicable(Base.get, el) ? Base.get(el) : missing
        el
    end
end
