fix: Scrolling along edges breaks text editing - #135
Merged

Conversation
Existing Gutenberg `preventFocusCapture` logic relies upon `pointerdown` and `pointerup` events for temporarily disabling all text blocks `contenteditable` status. This is down to mitigate issues with block selection for `flex` elements. However, `pointerup` events are not always triggered on touch devices when a touch turns into a swipe. When you scroll with your finger outside of the block canvas, the `pointerup` callback is never invoked. Scrolling twice or more leads to a stale `value` in the callback, and a state where `contenteditable` is perpetually disabled.

Fix is good! I was able to reproduce the problem in trunk but not with this branch

…ories Resolves 29 Dependabot advisories in the dev dependency tree. None of these packages ship in the iOS/Android app bundle -- they are build, lint, and local-WP (`@wordpress/env`) tooling. In-range bumps: - `vite` 8.0.5 -> 8.2.1 (direct devDep; floor raised to `^8.0.16`) #134 #135 - `shell-quote` -> 1.10.0 (critical #133) #165 - `fast-uri` -> 3.1.5 #163 #164 #179 #206 #207 - `js-yaml` -> 3.15.1 / 4.3.1 #157 #158 #167 #168 #200 #201 - `brace-expansion` #160 #166, `immutable` #161 #162, `tmp` #131, `fast-xml-builder` #122 #123, `simple-git` #119, `@babel/plugin-transform-modules-systemjs` #126 Scoped `overrides` (parents exact-pinned the vulnerable version): - `ws` -> 8.21.0, keeping 7.5.13 for `react-devtools-core` #138 #153 - `qs` -> 6.15.2 under `@wordpress/env` #130 - `minimatch` -> 9.0.9 under `@typescript-eslint/typescript-estree` #65 - `@babel/core` -> 7.29.7 under `@wordpress/babel-preset-default` #154 Not addressed here: `electron` (33 alerts) and its bundled `got` (#33) are pinned by `react-devtools@7.0.1` -- already the latest, and npm's only "fix" is a breaking downgrade to `react-devtools@1.0.5`. Runtime-scope advisories (`seroval`, `nanoid`, `postcss`, `showdown`, `uuid`) are out of scope for a dev-only bump. Verified: `npm run test:unit` (202 passing) and `npm run build` green.
