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 7a5b070e95 (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.
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.
It's a straightforward change to support new, common, keyboard commands
Note that I've tested this locally with Chrome on my Mac but it seems that CI doesn't want to pass Chrome tests - it's running on ubuntu though. Does this mean that I should introduce per-platform editing commands? At the moment there is only a single [`macEditingCommands`](0ed33522c5/packages/playwright-core/src/server/macEditingCommands.ts) file.

This patch introduces 109 "#smoke" tests - a subset of tests that makes
sure that basic Playwright functionality works. This set is loosely
defined; feel free to add/remove tests to the set. The only goal is to
keep this set minimal & fast to run.
I tried to pick tests so that various parts of Playwright functionality
are exercised.
