Typing in “Width” Block Input Causes Duplicate Blocks

[mumal123]

Description

While testing Music Blocks, I noticed that adding a “width” block triggers an editable blue input box at the top of the screen.
When I type random text (e.g., “dkd” or “d do”) into that box, it unexpectedly causes duplication of other blocks in the workspace.
This seems unintended and affects the workspace layout.

Expected Behavior

Typing into the width block’s value input should only modify the width parameter, not duplicate blocks or affect the workspace visually.

How to Reproduce

Open Music Blocks(https://musicblocks.sugarlabs.org/)
or run it locally (127.0.0.1:3000).

Add a “width” block to the workspace.

Observe that a blue editable text box appears at the top.

Type any random letters into that box.

Notice that some blocks get duplicated or glitch visually.

Environment:

Browser: Chrome 141.0.0.0

OS: Windows 11

@omsuneri @HarshJS30 The WidthBlock is a read-only reporter. Its job is to report the current canvas width, which it calculates in its arg and updateParameter() methods. It is not designed to receive or set a value.
so can't we just do this
// Width is a read-only value, so it shouldn't be a parameter
this.parameter = false;
instead of true ?
correct ?
