The El HTML template parser (native { } syntax introduced in 5cb13d6) strips
spaces from text nodes, drops & from HTML entities (' → 39;), and breaks
hyphenated attribute names (aria-label → aria - label). All other component
files were already converted to the extern el_*() function style in 2553a6b
which is immune to this issue. about.el was the only page still using the
broken template syntax. Restoring the raw string return style fixes all
rendering defects on /about.
