/**
* Matches block comment delimiters
*
* While most of this pattern is straightforward the attribute parsing
* incorporates a tricks to make sure we don't choke on specific input
*
* - since JavaScript has no possessive quantifier or atomic grouping
* we are emulating it with a trick
*
* we want a possessive quantifier or atomic group to prevent backtracking
* on the `}`s should we fail to match the remainder of the pattern
*
* we can emulate this with a positive lookahead and back reference
* (a++)*c === ((?=(a+))\1)*c
*
* let's examine an example:
* - /(a+)*c/.test('aaaaaaaaaaaaad') fails after over 49,000 steps
* - /(a++)*c/.test('aaaaaaaaaaaaad') fails after 85 steps
* - /(?>a+)*c/.test('aaaaaaaaaaaaad') fails after 126 steps
*
* this is because the possessive `++` and the atomic group `(?>)`
* tell the engine that all those `a`s belong together as a single group
* and so it won't split it up when stepping backwards to try and match
*
* if we use /((?=(a+))\1)*c/ then we get the same behavior as the atomic group
* or possessive and prevent the backtracking because the `a+` is matched but
* not captured. thus, we find the long string of `a`s and remember it, then
* reference it as a whole unit inside our pattern
