  // Because we want an ellipsis on the left-hand side (e.g. "...longfilename.tex"), the
  // `log-entry-location` class has text laid out from right-to-left using the CSS
  // rule `direction: rtl;`.
  // This works most of the times, except when the first character of the filename is considered
  // a punctuation mark, like `/` (e.g. `/foo/bar/baz.sty`). In this case, because of
  // right-to-left writing rules, the punctuation mark is moved to the right-side of the string,
  // resulting in `...bar/baz.sty/` instead of `...bar/baz.sty`.
  // To avoid this edge-case, we wrap the `logLocationLinkText` in two directional formatting
  // characters:
  //   * \u202A LEFT-TO-RIGHT EMBEDDING Treat the following text as embedded left-to-right.
  //   * \u202C POP DIRECTIONAL FORMATTING End the scope of the last LRE, RLE, RLO, or LRO.
  // This essentially tells the browser that, althought the text is laid out from right-to-left,
  // the wrapped portion of text should follow left-to-right writing rules.
