Cherry-pick 5dbb993a from release branch

Cherry-pick 5dbb993:

Removing verbose debug statement when getting properties for property dialog (which happens as the user scrubs the timeline)

[SuslikV]

Can this be transformed to the debug log level?

Edit: There were thoughts: #2895 that there could be more that just "info" level of verbosity in the logs. But nothing changed since these posts.

Merging, because this is hella annoying.

Can this be transformed to the debug log level?

If someone implements off-by-default debug logging, sure, I suppose it could be. Though I somewhat question the usefulness of spewing out the entire property definition of every frame the user previews, even for debugging.

But, I won't disagree that we could really use another level of logging, one that defaults to disabled. Along with a command-line switch to enable it for just the current session, so you don't have to edit your settings (and then remember to turn it off again.)
