math doesn't render if surrounded by certain characters

[Nico Schlömer]

MWE:

$-style math cannot be preceeded by most characters.

$x$ a$x$ 1$x$ -$x$ '$x$ "$x$ ($x$ [$x$ {$x$ /$x$

$x$ a$x$ 1$x$ -$x$ '$x$ "$x$ ($x$ [$x$ {$x$ /$x$

$-style math cannot be succeded by alphanumeric characters:

$x$a $x$1

$x$a $x$1

Dollar-backtick math cannot be preceeded by an alphabetic character:

a$`x`$

a$x$
