Document Language settings not honoured when hovering mouse over text

[Qchristensen]

Steps to reproduce:

1. Open: https://en.wikipedia.org/wiki/Template:Lang
2. Find the line which has "Je suis française" (this line provides the template Wikipedia uses and then the text with the right formatting so should be read first in English and then in French).
3. Read the line with the keyboard.
4. Hover the mouse over the text and read it that way.

Actual behavior:

When using the mouse to read text, the "Lang" HTML instruction is ignored and the text is read in the same language as everything else (English in this case).

When reading with the keyboard, the "Lang" tag is honoured as expected.

Expected behavior:

Honour the lang tag when reading with the mouse as well.
