Angular SASS (.scss) 剝離屬性。如何防止這種情況發生，以便我可以嵌入重複的屬性以實現跨瀏覽器相容性？

要複製，請建立一個新的 Angular 7.2 專案

{ "name": "default-app", "version": "0.0.0", "scripts": { "ng": "ng", "start": "ng serve", "build": "ng build", "test": "ng test", "lint": "ng lint", "e2e": "ng e2e" }, "private": true, "dependencies": { "@angular/animations": "~7.2.0", "@angular/common": "~7.2.0", "@angular/compiler": "~7.2.0", "@angular/core": "~7.2.0", "@angular/forms": "~7.2.0", "@angular/platform-browser": "~7.2.0", "@angular/platform-browser-dynamic": "~7.2.0", "@angular/router": "~7.2.0", "core-js": "^2.5.4", "rxjs": "~6.3.3", "tslib": "^1.9.0", "zone.js": "~0.8.26" }, "devDependencies": { "@angular-devkit/build-angular": "~0.13.0", "@angular/cli": "~7.3.9", "@angular/compiler-cli": "~7.2.0", "@angular/language-service": "~7.2.0", "@types/node": "~8.9.4", "@types/jasmine": "~2.8.8", "@types/jasminewd2": "~2.0.3", "codelyzer": "~4.5.0", "jasmine-core": "~2.99.1", "jasmine-spec-reporter": "~4.2.1", "karma": "~4.0.0", "karma-chrome-launcher": "~2.2.0", "karma-coverage-istanbul-reporter": "~2.0.1", "karma-jasmine": "~1.1.2", "karma-jasmine-html-reporter": "^0.2.2", "protractor": "~5.4.0", "ts-node": "~7.0.0", "tslint": "~5.11.0", "typescript": "~3.2.2" } }

將「teststyle」類別加入到元件中的任何元素。

Hello 
 

在元件對應的.scss檔中套用

.teststyle { background: #a64bf4; background: -webkit-linear-gradient(right, #6ab443, #04a95f, #00d421); background: -o-linear-gradient(right, #6ab443, #04a95f, #00d421); background: -moz-linear-gradient(right, #6ab443, #04a95f, #00d421); background: linear-gradient(right, #6ab443, #04a95f, #00d421); }

角度預處理器會刪除除第一個屬性和最後一個屬性之外的所有內容。 對應的css是這樣的。 -webkit-線性梯度、-o-線性梯度和-moz-線性梯度不是轉譯的css/js檔。這是一個 tarnspilation 問題，而不是瀏覽器問題。

當我使用直接 css 時，我看到了這一點，這是正確的。

還包括 angular.json
