Fixes focus and blur management when `page.locator(…).focus()` and `page.locator(…).type(…)` are used which was regressed by 7a5b070 (#13510).
#13510 relied on an implicit assumption that this (conditional) [`blur`](7a5b070e95/packages/playwright-core/src/server/injected/injectedScript.ts (L672)) call would always be followed by a call that resulted in a newly focused element via this [`focus`](7a5b070e95/packages/playwright-core/src/server/injected/injectedScript.ts (L674)) call.
However, some elements are [not focusable](https://html.spec.whatwg.org/multipage/interaction.html#focusable-area), so we were blurring incorrectly, and losing focus that we should have maintained.
Two regression tests were added that pass on the commit prior to 7a5b070e9507b622877a2af010373585f2184196 (and match manual testing/expectations):
* `page.locator(…).focus()`: _keeps focus on element when attempting to focus a non-focusable element_
* `page.locator(…).type(…)`: _should type repeatedly in input in shadow dom_
Additionally, a third test (_should type repeatedly in input in shadow dom_) was added to check the invariant from #13510 that states:
> This affects [contenteditable] elements, but not input elements.
and allows us to introduce the targeted fix (contenteditble check before blur) without breaking FF again.
And _should type repeatedly in contenteditable in shadow dom with nested elements_ was added to ensure the above fix works with nest contenteditble detection.
Fixes#14254.
This fixes a few issues:
- strict mode was producing false negatives if multiple query paths
lead to the same element being picked;
- in some cases the number of intermediate items in the list was
exponential and crashed quickly.
What changed:
- `visible` engine is a real engine now;
- `capture` selectors are transformed to `has=` selectors for
easier implementation;
- chained querying switched from a list to a set to avoid
exponential size.
We skip waiting for "visible" state that enforces non-zero size.
Other invisible conditions like "display:none" fail during the
actual "scrolling" step and will retry.
feat: support experimental doc entries
- Params/options/members are marked as experimental in the docs.
- `experimental.d.ts` is generated that contains all types and
includes experimental features.
- `experimental.d.ts` is references in our tests so that we
can test experimental features.
- `fonts` option is restored as experimental.
Firefox has a bug: calling `node.focus()` does make the node focused,
but some internal "current contenteditable node" is not changed.
Blurring the previous one and focusing the new one helps.
- This supports `role=button[name=Hello]` similarly to CSS selectors.
- Does not change `_react` or `_vue` behavior that insist on quoting the string.
- Uses CSS notion of "identifier" characters.
