vscode appends git diff to commit message

[vscodebot]

• VSCode Version: 1.43.0
• OS Version: macOS Catalina 10.15.3

Steps to Reproduce:

1. Set vscode as default editor for git git config --global core.editor "code --wait"
2. Take following Angular component:

import { Component, ViewChild, ElementRef, OnInit } from '!angular/core';
import { ThemeConstantService } from '../shared/services/theme-constant.service';

!Component({
  templateUrl: './dashboard.component.html',
  styles: [
    `
      !media only screen and (min-width: 992px) {
        .completion-chart {
          width: calc(100% - 330px);
        }
      }
    `
  ]
})
export class ProjectsDashboardComponent implements OnInit {
  constructor(private colorConfig: ThemeConstantService) {}
  themeColors = this.colorConfig.get().colors;
  blue = this.themeColors.blue;
  blueLight = this.themeColors.blueLight;
  cyan = this.themeColors.cyan;
  cyanLight = this.themeColors.cyanLight;
  gold = this.themeColors.gold;
  purple = this.themeColors.purple;
  purpleLight = this.themeColors.purpleLight;
  red = this.themeColors.red;
  transparent = this.themeColors.transparent;

      }
    `
  ]

The issue does not appear if only small parts (like properties) are deleted. I suspect that arrays are the problem.
What looks suspicious is this colour for the bracket:
