Bug or "neat party trick"

Reposting my answer from SteveF's thread http://community.logos.com/forums/t/48395.aspx which is in the private FSB beta forum, since the bug occurs in the Community Notes pane regardless of whether the FSB is used or any other resource. Maybe some users can chime in with other OS / browsers whether they have been deprived of this feature or not:

On the FaithLife Study Bible beta page:

When in "More" I "delete" (successfully) a post THEN immediately again try to "reply"  I cannot.

Instead I see a "bouncing" reply box -- vertically moving up & down on my monitor--until I hit the "refresh" button, at which time it apparently resets, ie. is back to normal stable position. [this is a "neat" party trick but a little unsettlingly when first encountered].

Hi Steve,

What OS and browser are you using?  Thanks!

Not Steve, but I can consistenly recreate this behaviour on Win 7 Home Edition, 32 Bit running Chrome.

It's not restricted to the FSB but happens as well in Community Notes elsewhere (tested ESV as well as Metaxas' Bonhoeffer to have a non-bible-indexed resource ).

Step 1 Add a Note (Or use a not-replied-to note from another user, such as Phil 4:2 from MJ Smith or mine in Phil 4:5 - it doesn't matter whether one replies to oneself or to another user)

Step 2 Reply to that Note (in my tests it worked only in the first reply - not with a second reply e.g. in Phil 4:1)

Step 3 Delete the reply

Step 4 Hit Reply in the first note again to give you an edit box.

This edit box will bounce, but the Community Notes pane is not gone bad - you may now "like" the first note or even add another note etc: all is cool while edit box bounces happily. If you add another, this is sorted below, thus it bounces along 

"Bounce" means the edit box is being drawn and in the process the box height repeatedly increases and collapses. It draws a divider line, then the horizontal top line of the box and the vertical lines, thus the box is seemingly growing downwards. When the bottom line is drawn, the box collapses and starts drawing again.

If you try, you may even click into the box and enter text there. It never draws the Cancel/Reply buttons below the box to actually post the reply or cancel it.

To stop, one just needs to select another verse in the resource, which makes a Community Notes pane refresh.
