Motivation
Fix HTML elements incorrect visual state when replay.
The SDK incorrectly sent empty attribute mutations as
null
. Butnull
is also used for removed attributes, so instead setting the attribute to an empty string, the player removes the attribute, which may have an impact on the visual state of some elements.Changes
To fix the issue, this PR sends empty attribute mutations as an empty string instead.
Testing
I have gone over the contributing documentation.
