bug(Dialog, Form Field): The form field outline appearance label is cut of when it's the first element in a dialog

[Warwizza]

Is this a regression?

• [x] Yes, this behavior used to work in the previous version

The previous version in which this bug was not present was

No response

Description

I'm not sure if this is a regression as we used the legacy style form fields before we updated to Angular (material) v15

When placing a form field with appearance="outline" as the first element in a dialog I get the following result:

I'm using the mat-dialog-title and mat-dialog-content directives which will set the top padding of the content part to 0px

A simple workaround is to set a top padding of 5px, but this should work out of the box.

Reproduction

Steps to reproduce:

1. Open the following Stackblitz .
2. Click the Pick one button to open the dialog.
3. The dialog should focus the input and this shows the image.
4. Optional enter a value in the input field

Expected Behavior

I would expect to be able to see the full label when a form field is the first element in a dialog.

Actual Behavior

The top part of the label is cut off.

Environment

Angular CLI: 15.0.3 Node: 16.13.1 Package Manager: npm 8.1.3 OS: win32 x64

In the stackblitz from the "Reproduction" I've swithced to v14 and there's no issue. So, it looks like the regression issue.

The workaround which is applied to all mat dialogs in a project:

1. Define the below style in the "styles.css"

   .mat-field-inside-dialog-workaround .mat-mdc-dialog-title + .mat-mdc-dialog-content {
   padding-top: 4.3px;
   }

2. Configure global panelClass in the providers section of the root module ("app.module.ts")

   providers: [
   {provide: MAT_DIALOG_DEFAULT_OPTIONS, useValue: {panelClass: 'mat-field-inside-dialog-workaround'}},
   ]

Update (2024-06-24): the above workaround doesn't work since Angular 18

I've ended up using another workaround which sets the overflow of the mat-dialog-content to visible. Add the following to the styles.css of the project: mat-dialog-content { overflow: visible !important; }

I came across the same issue, but also on non-dialog specific use cases. The base problem seems to be that the label is outside the boundary of the mat-form-field.

Be aware that this can mess up mat-dialog-actions

This can help

mat-dialog-content form mat-form-field:first-of-type {
  margin-top:4px;
}

I now put it in my CSS of the component, but maybe suitable in the base-CSS (styles.css)

For tab-pages the same problem. I solved this by adding this to styles.css

form mat-tab-body mat-form-field:first-of-type {
  margin-top:6px;
}

Because each body has a "first" mat-form-field

I have the same problem...and I'd love a correction! (thanks for the temporary workarounds)
