Define inactive notebook arrows CSS style
This is a minor edit to the default CSS theme. When the first or last notebook tab is selected and a filter window is open, the arrow selector is inactive and takes on a different style. Currently this is not defined, resulting in overly dark colors in the Light theme:
This edit adds @strong-border-color
to the backgrounds of notebook header tabs arrow:disabled
, notebook header tabs arrow:hover
.
Feedback on the color scheme appreciated!
