Symbols appear at random places

[AlexanderZeilmann]

As mentioned in the issues siegebell#42 and siegebell#53 of the original vsc-prettify-symbols-mode, symbols sometimes appear at random places. This bug sadly also exists in conceal.

As far as I can tell, the symbols that appear randomly are actually present somewhere else in the file.
So it is not random symbols, but only a random placement.

Interestingly, the random symbols often also appear in files that should not be touched at all. For example, I configured conceal to only do substitutions in *.tex files, however, I also get substitutions in my settings.json.

Maybe the same bug, maybe not:
Using a configuration like

{
    "ugly": "\\\\Omega",
    "pretty": "Ω",
    "post": "\\b|_"
}

sometimes leads to the partial substitution, where \Omega is substituted by \Ωmega, where only the O is replaced by an Ω.

So far I do not know what triggers the bug. But it appears very often when working on files for some time.
The issues sadly cannot be fixed by disabling and enabling conceal.

I am using conceal 0.2.3 and the latest version of vsc:

This is indeed very strange, and probably the main bug of the repo I forked. It's gonna take some digging but I'll see if I can find anything

Disclaimer: I claim no actual understanding of this code, just saw this in the network graph.

Oooh interesting, I'll check this out, it seems promising
