Subject: Fix: Do not set text on canvas element if it didn't change.
X-Git-Url: https://git.mdrn.pl/fnpeditor.git/commitdiff_plain/890e3143c7146ecc4b1982e13369134d518864df

Fix: Do not set text on canvas element if it didn't change.

On setting the same text on a text node Chrome does nothing,
but FF triggers ContentObserver handler.
