Cannot work when text characters > ~4099

```diff
-  if (strlen(_text) > SKIP_PARSE_THRESHOLD) {
-    return textstyle_buffer;
-  }
+  // if (strlen(_text) > SKIP_PARSE_THRESHOLD) {
+  //   return textstyle_buffer;
+  // }
```

Before comment `libs/tm-parser/textmate/textmate.cpp`, It cannot work for too long text.
After comment, it will not highlight when text characters > ~4099.
