JSX/TSX expansion reverts to class instead of className when using multiplication operator

Reproduction:

.vimrc:

Plug 'mattn/emmet-vim', { 'for': ['html', 'javascriptreact', 'typescriptreact'] }
autocmd BufNewFile,BufRead *.tsx set filetype=typescriptreact
autocmd BufNewFile,BufRead *.jsx set filetype=javascriptreact

foo.tsx:

.foo>.bar*5

results in

<div class="foo">
  <div class="bar"></div>
  <div class="bar"></div>
  <div class="bar"></div>
  <div class="bar"></div>
  <div class="bar"></div>
</div>

Expected:

<div className="foo">
  <div className="bar"></div>
  <div className="bar"></div>
  <div className="bar"></div>
  <div className="bar"></div>
  <div className="bar"></div>
</div>

When not using the multiplication operator, the correct expansion is observed:

.foo>.bar

results in

  <div className="foo">
    <div className="bar"></div>
  </div>

Start by reproducing the expansion in foo.tsx with the provided emmet-vim configuration, comparing .foo>.bar*5 with .foo>.bar. Trace the JSX/TSX expansion path and verify that multiplication produces className for every generated element, matching the expected output.
