Chart Drawings Are Not Consistently Visible Across Different Timeframes

There appears to be an issue with chart drawings such as trendlines and other drawing tools.

When I create a drawing on one timeframe, the drawing is not consistently displayed when switching between different timeframes. Some timeframes show the drawing while others do not, even though the drawing should remain visible across timeframes.

Example

For example:

1. Open a chart on the 1D timeframe.

2. Draw a trendline on the chart.

3. Switch to the 15-minute timeframe — the trendline is visible.

4. Switch to the 7-minute timeframe — the trendline disappears.

5. Switch to the 5-minute timeframe — the trendline becomes visible again.

So, the drawing is visible on some timeframes but missing on another timeframe in between.
