Mike it looks like this might be related to native text selection, do you have time to take a look?

This is HTML/CSS, so maybe this is something Ray or someone else in Taipei could help with.

I believe there is some CSS rule that you can use to prevent text selection on an element, and I thought we were using that already.

The selection handles present when clicking on any margin region. 

As Margaret said, a simple line of css rule could handle it. I'm not sure whether it is the answer to this bug, but if the patch looks reasonable, we could just land it. Thanks.

If you want to request uplift for 48, this could still make it into beta 6.

Comment 11

[Gerry Chang [:gchang]]

Hi Ray,
Since this patch also affects 48, do you want to uplift this for 48 if this patch is not too risky?

Comment 12

[Gerry Chang [:gchang]]

Track this as this is a regression in 48.

Comment 13

[Ray Lin[:ralin]]

sorry for the late reply. 

I don't think this bug is too risky, it occurs only when user mis-click on the panel.

Comment 14

[Gerry Chang [:gchang]]

Hi Ray,
Can you create a uplift request for 48?
