Use the same value synchronization function on number blur#11746
Conversation
I updated ReactDOMInput.synchronizeDefaultValue such that it assignes the defaultValue property instead of the value attribute. I never followed up on the ChangeEventPlugin's on blur behavior.

I don't think so. Though the controlled input guard triggers above this line. It is not apart of this specific block.

But you asked! So we could probably improve it. Something like:
// Focused number inputs do not update their defaultValue on change. This
// avoids unexpected value changes in Chrome while the user is typing. On blur,
// we need to synchronize the defaultValue to match standard input behavior.

Is there any difference in observable behavior here? Does this need a fixture? |

I don't think so. We just need to test the number input fixtures. |

…1741) * Ensure value and defaultValue do not assign functions and symbols * Eliminate assignProperty method from ReactDOMInput * Restore original placement of defaultValue reservedProp * Reduce branching. Make assignment more consistent * Control for warnings in symbol/function tests * Add boolean to readOnly assignments * Tweak the tests * Invalid value attributes should convert to an empty string * Revert ChangeEventPlugin update. See #11746 * Format * Replace shouldSetAttribute call with value specific type check DOMProperty.shouldSetAttribute runs a few other checks that aren't appropriate for determining if a value or defaultValue should be assigned on an input. This commit replaces that call with an input specific check. * Remove unused import * Eliminate unnecessary numeric equality checks (#11751) * Eliminate unnecessary numeric equality checks This commit changes the way numeric equality for number inputs works such that it compares against `input.valueAsNumber`. This eliminates quite a bit of branching around numeric equality. * There is no need to compare valueAsNumber * Add test cases for empty string to 0. * Avoid implicit boolean JSX props * Split up numeric equality test to isolate eslint disable command * Fix typo in ReactDOMInput test * Add todos * Update the attribute table
