When document line count exceeds 500, Latex decorations for multi-line math fail to render properly

[Kruse002]

In any document that exceeds 500 lines and uses multi-line math excessively, the app will fail to interpret multi-line math correctly and instead attempt to render any non-math text that occurs between instances of multi-line math.

Steps to reproduce:

1 - With Markless' Latex math rendering enabled, begin a new .md document.
2 - Enter the following:

$$
\frac{1}{2}
$$
Normal text

...followed by the enter key. Observe that 1/2 renders as math while the normal text remains normal.
3 - Press Ctrl+A and Ctrl+C. Then hold Ctrl+V until the document line count exceeds 500.

Expected result: The text surrounded by double dollar signs continues to render as math.

Actual result: The text outside the double dollar signs gets rendered as math while the \frac{1}{2} lines are displayed as literal text.

Note: The failure occurs whenever the code in runner.js, line 157, in the definition of function updateDecorations is triggered. A temporary workaround is possible at the risk of performance issues. Open %USERPROFILE%.vscode\extensions\tejasvi.markless-1.0.7\src\main.js and navigate to "document.linecount>500" at line 57. Modify the value of 500 to be arbitrarily high.
