Created attachment 1701258 [details] YAML editor See screenshot. The line number for the current line in the YAML editor clearly doesn't have enough contrast to meet accessibility requirements. This might be a regression after the recent Patternfly update.
Checked on OCP 4.6 cluster with payload 4.6.0-0.nightly-2020-07-25-091217 On yaml edit page, the current line number is white on dark gray. The bug is fixed.
