…acebook#35656) autoFocus is a global HTML attribute per the spec, but React only handled it for button, input, select, and textarea. This change treats autoFocus as a global attribute so it works on any focusable element including anchor tags, div with tabIndex, dialog, details, etc. Changes: - finalizeInitialChildren: default case now returns !!props.autoFocus - commitMount: default case now calls .focus() when autoFocus is set - Added tests for <a autoFocus> and <div tabIndex={0} autoFocus>
…#35490) Fix two regex patterns in parseStackTrace.js vulnerable to catastrophic backtracking: 1. firefoxFrameRegExp: replace overlapping .*".+" with non-overlapping character classes [^@"]*(?:"[^"]*"[^@"]*)* 2. CHROME_STACK_REGEXP: simplify detection regex from /^\s*at .*(\S+:\d+|\(native\))/m to /^\s*at /m to eliminate the O(n^2) backtracking between .* and \S+

Summary
This PR addresses two open issues:
1. Support autoFocus as a global HTML attribute
(#35656)
autoFocusis a [global HTMLattribute](https://developer.mozilla.org/en-US/docs/W
eb/HTML/Global_attributes/autofocus) per the spec,
but React only handled it for
button,input,select, andtextarea. This change treatsautoFocusas a global attribute so it works onany focusable element — anchor tags,
<div tabIndex={0}>,<dialog>,<details>, etc.Changes:
finalizeInitialChildren: default case now returns!!props.autoFocuscommitMount: default case now calls.focus()when
autoFocusis set<a autoFocus>and<div tabIndex={0} autoFocus>2. Fix ReDoS vulnerabilities in stack trace
parsing (#35490)
Two regex patterns in
parseStackTrace.jsarevulnerable to catastrophic backtracking:
firefoxFrameRegExp:(?:.*".+")?[^@]*contains overlapping quantifiers. Replaced with
[^@"]*(?:"[^"]*"[^@"]*)*using non-overlappingcharacter classes.
CHROME_STACK_REGEXP:.*(\S+:\d+|\(native\))causes O(n²) backtracking. Simplified to
/^\s*at /m.
