Codecell size changes with selection

[juhasch]

When selecting a complete line in a codecell, the vertical size of the codecell box changes in Firefox. The codecell has two empty lines, in order to be able to select a line.

Unselected cell:

Selected cell:

Changing style.min.css
.CodeMirror-scroll{overflow-y:hidden;overflow-x:auto;}
to
.CodeMirror-scroll{overflow-y:hidden;overflow-x:hidden;}
makes this go away.

We will have to study this very carefully before making changes as these
things a super subtle...

Sure. I see this on master with all PCs (Linux or Windows) using Firefox. Not on Chrome, though.

[ellisonbg]

OK we will test this on Mac as well.

@juhasch can you update to master? There was a recent update to CodeMirror that may help.

Could this be related to the wrap problem ?

[ellisonbg]

It actually could be..

Probably not - this is unique to Firefox, and the wrap problem is unique to Chrome.

[juhasch]

I am running current master. I updated the submodules too, so codemirror should be up to date.

[minrk]

Well, one can always hope. Do you have any custom CSS?

[juhasch]

I double checked on Windows and did a clean install of IPyton master on Linux. Removed everything from the profile and no special CSS.

[minrk]

Okay, just checking. Thanks, I will dig into the Firefox madness.

[minrk]

After a bit of digging, I just punted by setting this CSS property as you described, only on Firefox. Since Firefox already totally ignores proper scrolling behavior, there is no benefit to having overflow-x: auto there.

Oh the wonders of standards...
Thank you.
