Bug 266852 – Remove -webkit-column-progression and -webkit-column-axis properties

• Component: Layout and Rendering
• Status: NEW

[Ahmad Saleem]

Hi Team,

While looking through Blink's commit, I came across another potential clean-up:

Blink Commit - https://chromium.googlesource.com/chromium/blink/+/b8e807bcea9f03c4a4cd7aa4a7fb7e2b7ac7acc2

Just wanted to raise to get input, whether we still have any internal usage or it is safe to remove.

NOTE - I just checked that we have tests but didn't check, if we still have implementation.

Thanks!

Ahmad, I think these can be safely removed.
I searched and didn't find any instances apart in the codebase of WebKit.

Ahmad, doing a last check internally about dependency on the content.
