Environment

• Package version(s): "@blueprintjs/core": "^5.10.0",
• Operating System: Mac OS 14
• Browser name and version: Chrome 122

Code Sandbox

Steps to reproduce

See the linked code sandbox

1. Open a Toast with timeout of 0. Note that focusing the toast will dismiss it (without clicking the 'x')
2. Note that with an explicit timeout (e.g. 100_000) this is not the case; Toast remains open after focusing.
3. timeout: Infinity is poorly behaved; Toast immediately closes

Actual behavior

See above and also screen recording from sandbox:

Screen.Recording.2024-03-14.at.11.45.53.AM.mov

Expected behavior

Toast with timeout: 0 should not dismiss early. timeout: Infinity should also behave the same as timeout: 0

Thanks for the bug report @dylangrandmont! Fix for 0 here #6783. We should probably handle Infinity better as you mentioned.

Will leave this open for the Infinity part of the problem.

Thanks, @gluxon! Let's also track adding a test case as part of fixing this issue.
