Description

• Admin settings lists and files table: pressing Space on a focused row checkbox toggles that row instead of the last selected one, in admin Groups, Users and Spaces and in the files table, tiles view and Shared with me.
• Unchanged: Space with the focus elsewhere still toggles the last selected row and doesn't scroll the page.

How Has This Been Tested?

• test environment: unit tests (Vitest), browser tests (Playwright) against a local OpenCloud
• test case 1: Space on a focused checkbox leaves the toggle to the checkbox, Space elsewhere toggles the last selected row and prevents the default
• test case 2: browser: select row 1, tab to row 3's checkbox, Space selects row 3, again deselects it, in all six lists; arrow keys, Shift+Arrow and typing spaces in inputs unchanged
