WASM: text inside row![] inside button() clips to single character

[JagritGumber]

Description

When targeting wasm32-unknown-unknown, placing a row![] with multiple text() widgets inside a button() causes the text content to be clipped to a single character. This does not occur on native (Linux/Vulkan).

Reproduction

// BROKEN on WASM — shows "I" instead of "Import"
button(
    row![
        text(icon_char).font(icon_font).size(16),
        text("Import").size(13),
    ]
    .spacing(6)
    .align_y(Alignment::Center)
)
.padding([6, 12])
.width(Length::Fill)
.style(primary_button_style)

// WORKS on WASM — shows full "Import"
button(
    text("Import").size(13).center()
)
.padding([6, 12])
.width(Length::Fill)
.style(primary_button_style)

Observations

• Single text() inside button() renders correctly on WASM
• row![] inside button() causes text to clip to 1 character on WASM
• Same code renders correctly on native (Linux, Vulkan backend)
• .width(Length::Fill) on the button may be a contributing factor, but removing it still shows the clipping when row![] is present
• text() with explicit .font() is not the cause — tested with default font and explicit font, both clip inside row![]
• row![] outside of button() (e.g., in a container) renders text correctly

Environment

• iced 0.14
• Target: wasm32-unknown-unknown
• Built with trunk 0.21.14
• Browser: Chrome (WebGPU enabled)
• Works correctly on: Linux native (Vulkan)

Workaround

Use a single text() widget inside button() instead of row![]. For buttons that need an icon + label, either concatenate them in one string or place them outside the button.
