+From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001
+From: Alex Rudenko <alexrudenko@chromium.org>
+Date: Thu, 20 Nov 2025 11:18:30 +0100
+Subject: Fix element tree flickering with node inspection
+
+Regressed in https://crrev.com/c/6888910. The highlighting in the tree
+outline emits the INSPECT_MODE_WILL_BE_TOGGLED on the overlay model
+causing the tree to clear the highlight immediately. This CL
+recovers the logic missed in the https://crrev.com/c/6888910
+to prevent re-entrancy during highlighting.
+
+Fixed: 462120622

+Subject: remove obsolete NoArrayBufferZeroFillScope
+
+Replace the scope in favor of the V8 api added in
+https://chromium-review.googlesource.com/c/v8/v8/+/5679067
+
+Ports changes from
+1) https://github.com/nodejs/node/commit/869ea331f3a8215229290e2e6038956874c382a6
+2) https://github.com/nodejs/node/commit/ef9dc0857a73610f5de5dc9f37afd0a927c4c17f
+3) partially from https://github.com/nodejs/node/commit/e0a71517fef4ca83f2d40d2d1600022bc82a7f9f
+
+This is needed to remove dependency on the zero_fill_field_
+that is exposed to JS

+Subject: src: handle DER decoding errors from system certificates
+
+When decoding certificates from the system store, it's not actually
+guaranteed to succeed. In case the system returns a certificate
+that cannot be decoded (might be related to SSL implementation issues),
+skip them.

+Subject: Reduce stack memory consumption in BytecodeGenerator
+
+Using a SmallVector with 64 stack-allocated entries is not great
+for functions that can be used in deep recursions, so this patch
+replaces that with a ZoneVector.
+By allocating any backing store only when it's actually needed,
+and presizing that initial backing store when that happens, this
+should have similar performance while using a lot less stack space,
+allowing us to compile more deeply nested expressions.
+
+For the highly artificial example of a function full of nested
+empty blocks `function f() {{{{{...}}}}}`, this increases the max
+nesting level from around 670 to around 2600. With more aggressive
+inlining in official builds, it can have similar effects on patterns
+that don't even call `VisitStatements()` recursively.
+
