  "message": "Updated UMA to detect missing first-paint signal at top frame\n\nBehind a flag we already have a fix for the bug.  The fix suppresses\ninput to the page until first paint signal arrives.  Before we flip the\nflag, we want to make sure that the topmost frame always receives the\nsignal, in order to rule out the possibility of input event starvation.\n\nOBSOLETE_HISTOGRAM[PageLoad.Internal.SuppressedEventsCountBeforePaint]\u003dReplaced by PageLoad.Internal.SuppressedEventsCountBeforePaint2\nOBSOLETE_HISTOGRAM[PageLoad.Internal.SuppressedEventsTimingBeforePaint]\u003dReplaced by PageLoad.Internal.SuppressedEventsTimingBeforePaint2\nOBSOLETE_HISTOGRAM[PageLoad.Internal.SuppressedInteractionsCountBeforePaint]\u003dReplaced by PageLoad.Internal.SuppressedInteractionsCountBeforePaint2\n\nBug: 1255485\nChange-Id: Ic87bae3a2cd7364740ffb5d4071b25b0f9452a8f\nReviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/5142727\nCommit-Queue: Mustaq Ahmed \u003cmustaq@chromium.org\u003e\nReviewed-by: Ian Clelland \u003ciclelland@chromium.org\u003e\nReviewed-by: Robert Flack \u003cflackr@chromium.org\u003e\nCr-Commit-Position: refs/heads/main@{#1254608}\n",
