Description
Starting in Blockly 12.0.0-beta.6, using built-in fields like FieldNumber or FieldTextInput can result in a RangeError: Maximum call stack size exceeded.
This is caused by the the introduction of an accessor in the FieldInput class (#9011). While the code looks correct, when compiled with common tools (e.g. Webpack/Babel), the call to super.size_ = ... is sometimes transpiled to this.size_ = ..., causing infinite recursion at runtime. This affects any project that uses FieldNumber, FieldTextInput, or other FieldInput subclasses.
This is a bundler-sensitive issue triggered by the recent introduction of an accessor for size_.
Reproduction steps
- Use 12.0.0-beta.6
- Add any block with a
FieldNumberorFieldTextInput
