Use "user-select: none" to provide a visual cue about copy/paste JS magic
Summary:
- For line numbers, use "user-select: none" to make them unselectable. This provides a stronger visual cue that copy/paste is enchanted.
- In Paste, make it look sensible again after the blame-on-blame refactor in Diffusion. See also TODO to share this code formally.
- In Diffusion, use the "phabricator-oncopy" behavior.
NOTE: I left blame/commit columns selectable in Diffusion, since you might reasonably want to copy/paste them?
NOTE: In Differential, the left side of the diff still highlights, even though it will be copied only if you select part of a line on the left and nothing else. But this seemed like a reasonable behavior, so I left it.
Test Plan:
- Looked at Paste. Saw a nice line number column. Selected text, got the expected selection. Copied text, got the expected copy.
- Looked at Diffusion. Saw a nice line number column, still. Selected text, got expected selection. Copied text, got expected copy.
- Looked at Differential. Highlighted stuff, got expected results. Copied stuff, got expected results.
