While reporting #1942442: The checkboxes in the "Content language settings" page disable translatability when unchecked..., I was clicking around the elements in the "Content language settings" page (/admin/config/regional/content-language) in order to copy-paste text etc. and I've noticed that when you click on a bundle label, the respective checkbox from the "TRANSLATABLE" column is checked/unchecked. Is it just me or is this non-standard behavior?
For example, try this with the "Show language selector on create and edit pages" checkbox in the very same page:
1. try selecting the text of that check box with your mouse: checkbox state untouched
2. once done, click somewhere else outside, but near the text to deselect it: checkbox state still untouched
Try the same steps with the bundle labels:
1. try selecting the text with your mouse: checkbox state untouched
2. once done, click somewhere else outside, but near the text to deselect it: checkbox state flipped
